"Moving the decimal point" is an easy way to accomplish some multiplications or divisions.
If you have a number and you need to multiply it by 10, you should go through
the process of multiplication as you've learned to do it, and then when you finish,
LOOK at the product you've produced and SEE that it's the same as the original
number but with its decimal point moved one place to the right. Then, forever after,
you'll remember that if you need to multiply a number by 10, simply move its decimal
point one place to the right, and your multiplication will be done.

Reversing this, you are dividing by 10 by moving the decimal point to the left. For example, take 73. If you move the decimal point to the right you get 7.3. This is the same as: 73/10 = 7.3. If you move a decimal point 2 spaces to the right, you are multiplying by 100, or more generally if you move the decimal point n spaces to the right, you are multiplying by 10^n.
