If I have to find the quotient q and the remainder r and: a = -5286 b = 19 How do I go about writing down the steps for this algorithm? I know what the answer will be, but I need to be able to use the division algorithm to prove my answer. Like I know if: b > 0 and a < 0 (which in this case is true), then since -a > 0, a = (-q)b - r (where 0 <= r < b). But how would I know that q is equal to -279 and that the remainder is 15? (Pretending that I didn't the know answer already.) Thanks.
