Add or substract (depending on the sign) the denominator from the numerator till you have a number between 0 (included) and the denominator (not included).

You can define a function like this: def divide(n,d): rem = 0 quotient = 0 while True: if n < d: rem = n break else: n -= d quotient += 1 return quotient, rem Full code available here: https://code.sololearn.com/cLPbxIoU77mN

Example: 14 % 5: 14 - 5 = 9 9 isn't between 0 and 5, so we loop. 9 - 5 = 4 4 is between 0 and 5 and is the rest we are looking for.
