Hello friends! Today, we’re going to learn about something called long division. But first, do you remember what it means to divide? It’s like sharing something equally among friends. Cool, right?
When we divide, the number we want to split is called the dividend, and the number we divide by is called the divisor. So, in division, we split the dividend by the divisor.
Let’s try an example: dividing 125 by 5. Here, 125 is the dividend, and 5 is the divisor. Knowing your multiplication tables is super helpful for this. Do you remember them?
Imagine we have 125 astronauts and 5 spaceships. How do we know how many astronauts go in each spaceship? Let’s find out using long division!
To start, we need to see how many digits of the dividend we can use. The rule is that the part of the dividend we use must be equal to or greater than the divisor. Here, the 1 in 125 is less than 5, so we use the next number, making it 12.
Now, we think: what number times 5 is close to 12? Two times five is ten, which is close. Three times five is fifteen, which is too big. So, we write 2 above the division box and 10 below 12, then subtract. This gives us 2.
Next, we bring down the 5 from 125, making it 25. What number times 5 is 25? It’s 5! We write 5 next to the 2 above the box. Five times five is 25, so we write 25 below and subtract. We get 0, which means we’re done!
The answer, or quotient, is 25. This means each spaceship gets 25 astronauts. When there’s nothing left to divide, we check the remainder. If it’s zero, like here, it’s an exact division. If not, it’s called an inexact division.
That’s all for today! You’ve done a great job learning about long division. Keep practicing, and soon it will be super easy for you. See you next time!

Space Mission Division: Imagine you are planning a space mission with your friends. You have 100 space snacks and 4 spaceships. How many snacks will each spaceship get? Use long division to find out. Draw a picture of your spaceships and snacks to help visualize the division.
Division Detective: Become a division detective! Look around your home or classroom and find items that can be divided equally. For example, you might have 24 crayons and 6 boxes. How many crayons will go in each box? Write down your findings and share them with your class.
Story Time with Division: Create a short story where characters need to use long division to solve a problem. For example, they might need to divide treasure among pirates or share cookies at a party. Illustrate your story and explain how the characters used division to find a solution.

Hello friends! Today we are going to learn about long division.

But before we start, do you remember how to divide? I’m sure you do! To divide is to split an amount into equal parts. Awesome!
When we divide a quantity, that number is called the dividend, while the number that we divide by is called the divisor. In division, we divide the dividend by the divisor.

Let’s look at an example: let’s divide 125 by 5, where 125 is the dividend and 5 is the divisor. When dividing, we need to know the multiplication tables very well, as they are essential for long division. Do you remember them?
Imagine that we want to put 125 astronauts into five spaceships. How will we know how many astronauts will go in each spaceship? Let’s solve the operation. We can use long division to easily divide 125 by 5.
Let’s take a step-by-step look at how to do this. To start long division, we have to see how many digits of the dividend we have to use. The rule is that the number of the dividend we are going to divide has to be equal to or greater than the number of the divisor. In this case, the 1 in 125 is less than 5, so we have to choose the next number in the dividend to do the division. This means we will use the number 12.

Now we have to mentally calculate which number multiplied by the divisor is closest to the dividend. Which number multiplied by 5 gives us 12 or less? Indeed, two times five equals ten. We cannot use three because if we multiply it by five, it gives us fifteen, which is bigger than the dividend. If we use one, it is too small, and there is another one that is closer. So we write down 2 above the box and put the multiplication below the dividend—in our case, 10 under 12—and subtract.
In this case, the subtraction of 12 minus 10 gives us 2, so we write the result below. Now we bring the next number down from the dividend to get 25, which we will again divide by five. What number multiplied by 5 gives us 25 or is very close? 5! Great job! We write it down next to the 2 above the division box.
As 5 times 5 is 25, we write it down under the first 25 and subtract: 25 minus 25 equals 0. Exactly! This means the remainder of this division is zero. This means that if we divide 125 by 5, we get 25. We know this because we have no more numbers left to bring down from the dividend, so we’re done.
The result is also called the quotient of the division. That is the number of astronauts that each ship gets. In this case, we will put 25 astronauts into each spaceship.
When we don’t have any more numbers left to divide, we arrive at the remainder. If the remainder of the division is equal to zero, it is said to be an exact division. This means we are able to equally divide the dividend by the divisor without any numbers left over. When the remainder is not zero, we have leftover numbers after dividing the dividend by the divisor. This is called inexact division.
That’s all for today! You’ve been super attentive. You’ll see how easy it is for you to divide from now on. See you in the next class!
