When you divide, how do you turn the remainder into a fraction?

Put the remainder over the divisor.
If you were dividing 13 by 3 you'd have 4 (1/3). In this example 3 is the divisor.
You don't need to use the parentheses on paper, I used them here so there's no confusion.

oh ok! thank you so much! that really helped me! :)
