If you have 20/10, that equals 2. Then if you move the decimal place over 1 place then you have 2. If you divide 2 again by 10, then move the decimal place over in another place, it is equaling 0.2.
Say you have 30/10, which equals 3. Then move the decimal place
over 1 place to get 3. Divide 3 again by 10, and move
the decimal place over in another place. It is 0.3.
