How to Divide Numbers Ending in Zeros 

Division Review ⚡️

      Division is splitting a number into equal groups.

We can write any division in long division form, like this:

      Long division form makes dividing bigger numbers easier.

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

60 ÷ 2 = ?

Let’s start by writing this in long division form:

Now, here’s the trick:

      When a number ends in zero or more than one zero, we just divide the first digit in the dividend.

The first digit of the dividend, 6, divided by 2 equals 3!

Let’s put that right over the 6.

Next, we just bring up the zero. ⬆

We've found our answer, or quotient: 30!

Let's check if we got the correct answer by multiplying.

Yes, we got the right answer.

Great job! 🎉

Example 2

60,000 ÷ 2 = ?

First, write the problem in long division form.

What do we do next? 🧐

Since the number ends in zeros, we just divide the first digit in the dividend.

What is 6 ÷ 2?

You got it! It's 3.

We write that on top of 6.

Now, we just bring up the zeros.

Great job! ✅

Mental Math for Division

We can also use mental math, or math just in our head, to divide numbers that end in zeros.

Let’s try it.

1200 ÷ 3 = ?

Think about it like this. 👇

12 ÷ 3 = 4

How many zeros do we have? 🤔

Yes! 2 zeros.

Let’s add those to our answer.

This means: 

1200 ÷ 3 = 400

What happens if we have a problem like this:

280,000 ÷ 7 = ?

We divide the first 2 digits by 7:

28 ÷ 7 = 4

Then, we count the zeros in the dividend.

There are 4 zeros. We add these zeros back to 4.

280,000 ÷ 7 = 40,000

Great work! 🌟
