Division, or subtraction...
Let's change this problem to a similar one. For example, you have 9 cards and bought a book to put the cards in. Only 2 cards can fit on a page. How many cards would be left over. 9 divided by 2 is 4 with one left over.
I could also use subtraction... 9 - 2 = 7, 7-2 = 5, 5-2 = 3, 3-2 = 1, and 1 is left over.
HOpe this helps...
