Division is repeated subtraction, just like multiplication is repeated addition. If you divide 50 by 10, you get 5. This is also the question: How many times do you have to subtract 10 from 50 to get 0?
Multiplication is said to be rapid addition. It is like adding a large group of numbers at once. This is the same with subtraction and division. Division is essentially rapid subtraction. Let me know if you need more help.
