3 times with a remainder of 3
108/15 = 7 with a remainder of 3
15 times.
It go in 66,666,666 and 2/3 times
93 ÷ 15 = 6 with remainder 3
15: 15 one 6: 2, 3, 6 three
175/15= 11 and 2/3 or 11.66666667.
220 ÷ 15 = 14 2/3 ≈ 14.667
Let's say, 315 divided by 3. So, how many times does 3 go into 3? 1 time! So, 3x1=3. Then, Subtract 3-3=0. How many times does 3 go into 0? None! Does 3 go into 1? None! Subtract 1 and 0. You get one. Does 3 go into 1? None! Does 3 go into 15? Yes! 5 times! So, do 15-15. You get 0. Your final answer is 105 times.
