how can I calculate the rest of a division using only add and subtraction?

Answer 1

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).

Answer 2

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

Answer 3

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.
