// Note: This only works for positive values!
int divide(int numerator, int denominator) {
  int quotient = 0;

  while(numerator >= denominator) {
      numerator -= denominator;
      quotient++;
  }

  return quotient;
}

Initially I also thought the previous solution, but the final sentence of the text made me suspicious ("Find a fast way to do it."), so this is my solution:

def divide(num, den):
	quotient = 0
	quot_accumulator = 1
	den_accumulator = den

	while num >= den:
		if num < den_accumulator:
			den_accumulator = den
			quot_accumulator = 1

		num = num - den_accumulator
		quotient = quotient + quot_accumulator
		quot_accumulator = quot_accumulator + quot_accumulator
		den_accumulator = den_accumulator + den_accumulator
	
	return quotient
