Not OP, but I'm guessing he means this: 52/13: 52 - 13 = 39 39 - 13 = 26 26 - 13 = 13 13 - 13 = 0 count the subtractions and you get 4. As long as we're sticking to integer division, this works out fairly well. Here, a calculation with a remainder: 54/13: 54 - 13 = 41 41 - 13 = 28 28 - 13 = 15 15 - 13 = 2 (smaller than 13, so this is our remainder) 54/13 = 4 with 2 reaminder
