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.
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! 🎉
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! ✅
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
