Remember how dividing by 10 meant we reduced our number by a factor of $10$10? So, if we solve $444\div10$444÷10, our answer would be $44.4$44.4.

## The power

We can also solve $444$444 divided by $100$100 , and our answer is $4.44$4.44. So, the power of ten we are dividing by tells us how many decimal places our answer will have. $100$100 is $10^2$102, so our answer has $2$2 decimal places. Let's work through this in our video to see how it works.

## Larger powers

In our second video, we look at dividing by $10^6$106 and also see how we can work out a system for dividing by powers of $10$10. It might seem as if our decimal point is moving, but our digits are actually moving!

Remember!

When we divide a number by powers of ten, our digits move to the right one place for each power of ten.
