What is Division?

Imagine you have 12 cookies. 🍪

You want to share your cookies equally with **3 friends. **

How many cookies should each friend get? 🤔

That's right! 🤗

✅ Each person should get 4 cookies.

Do you know what we just did? 😎 We just used **division!**

Splitting a number into equal groups is called **division.**

👉 Here, we divided 12 cookies into 3 groups and got 4 cookies in each group.

The symbol for **division** is** ÷**

Let's write our first division equation:

12÷3 = 4

**12 ****divided by**** 3 equals 4**

😃 Every division equation has **3 main parts **- the **dividend,** the **divisor **and the **quotient.**

The **dividend** is the number being divided. This number is bigger!

The **divisor** is a number that divides the dividend equally. This number is smaller!

The **quotient **is the result we get after division.

Can you tell which is which? 🤔

Which number is the **dividend**?

15! Correct. 🤗

Which is the **divisor**?

5! Great work! 🤗

And which number is the **quotient**?

3! Correct again! 🤗

**Tip:** You'll also see division written like this:

This is called the **long division symbol. **

Writing division problems this way is helpful when you divide big numbers. You'll learn more about it later. 😃

Now, let's learn how to divide numbers.

First let’s use subtraction to understand division.

**To divide using subtraction,** subtract the smaller number from the bigger number over and over till you reach zero. Then, you count how many times you subtracted. That’s the answer!

Let’s try it! 😃

10 ÷ 2

✅ First, subtract 2 from 10 till you reach zero:

✅ Then, count the number of times you subtracted!

**5**! That’s your answer.

10 ÷ 2 = 5

__

👉 Let’s try another example!

9 ÷ 3

✅ First, subtract 3. Continue subtracting 3 until you get zero.

✅ Then, count how many times you subtracted.

3 times!

9 ÷ 3 = 3

Now, let's look at another way of understanding division.

Division using **repeated subtraction **works, but it's pretty slow.

👉 Use your multiplication skills instead to do division quickly.

Division is the opposite of multiplication.

If you know that 2 x 3 = 6, you also know that 6 ÷ 3 = 2!

Why is that?

Let's say you multiply a number by some factor.

You can then divide the product you get by that same factor to get the original number again.

Let's look at an example:

12÷ 3 = ?

Do you remember what number time 3 equals 12? 🤔

That's right!

4 x 3 =12

So you just figured out that 12 ÷ 3 = 4!

Now, let’s try division by grouping!

**To divide using grouping,** we'll divide the bigger number into groups of the smaller number.

👉 Let's look at an example.

10 ÷ 2 =?

This time, we'll make groups of 2, until we reach 10. Let's try it!

Then, count the number of groups you were able to make.

That's your answer.

10 ÷ 2 = 5

While this works, drawing groups is a bit slow. Try to memorize your division equations, just like with multiplication.

👉 Let’s try division with grouping again

6 ÷ 2 = ?

Divide 6 into groups of 2:

How many groups of 2 are there? 3!

6 ÷ 2 = 3

Great work! 🤗 Now, you understand the basics of division!

🎉 Now, you can move on to the practice!
