Dividing Numbers Ending in Zeroes

You’ve gotten really good at dividing with numbers from 0 to 12.

Now let's learn to divide some bigger **dividends**.

Do you remember the parts of a division equation?

Great! Now, let’s look at another way to write the same division problem.

This is called the **long form method **of division.

When do we do use the long form?

👉 When we need to do long division for bigger numbers.

The division bar is called the **long division symbol.**

Let's learn to divide numbers that end in zeroes using the long division symbol!

**Example 1**

Let's solve this equation.

80 ÷ 2 = ?

Let’s start by putting this under our division bar:

👉 Now, here’s the trick!

When a number ends in zero (or more than one zero!), we just have to divide the first number.

We just divided 8 by 2. Do you remember the answer? 🤔

4! That’s it! ✅ Let’s put that right over the 8.

Now, here’s the best part! We just bring up the zeros!

That was easy!

**Example 2**

Let’s try this out once more with the same numbers:

8,000 ÷ 2 = ?

First thing: Use the **long division bar!**

Since the number ends in zeros, let’s divide 8 by 2.

Now, we just bring up the zeros.

Great job! ✅

We can also use mental math to divide numbers that end in zero.

Let’s try it out!

900 ÷ 3 = ?

Think about it like this.

9 ÷ 3 = 3

How many zeros do we have? 🤔

2! Let’s add those to our answer.

This means:

900 ÷ 3 = 300

What happens if we have a problem like this:

120,000 ÷ 6 = ?

We can also divide a 2-digit number. In this problem we’ll divide:

12 ÷ 6 = 2

Then, we count the zeros and add those to 2.

There are 4 zeros. That makes 20,000.

120,000 ÷ 6 = 20,000

Great work! 🤗 Now, you know how to divide numbers that end in zeros.
