# | Quotient1 | Quotient2 | Remainder1 | Remainder2 | Remainder | Final | Rewritten |
---|---|---|---|---|---|---|---|
1 | 87/-64 | -2 | 87 - (-64 x -2) | 87 - 128 | -41 | 87 = -2 x -64 + -41 | -41 = 87 - -2 x -64 |
2 | -64/-41 | 1 | -64 - (-41 x 1) | -64 - -41 | -23 | -64 = 1 x -41 + -23 | -23 = -64 - 1 x -41 |
3 | -41/-23 | 1 | -41 - (-23 x 1) | -41 - -23 | -18 | -41 = 1 x -23 + -18 | -18 = -41 - 1 x -23 |
4 | -23/-18 | 1 | -23 - (-18 x 1) | -23 - -18 | -5 | -23 = 1 x -18 + -5 | -5 = -23 - 1 x -18 |
5 | -18/-5 | 3 | -18 - (-5 x 3) | -18 - -15 | -3 | -18 = 3 x -5 + -3 | -3 = -18 - 3 x -5 |
6 | -5/-3 | 1 | -5 - (-3 x 1) | -5 - -3 | -2 | -5 = 1 x -3 + -2 | -2 = -5 - 1 x -3 |
7 | -3/-2 | 1 | -3 - (-2 x 1) | -3 - -2 | -1 | -3 = 1 x -2 + -1 | -1 = -3 - 1 x -2 |
8 | -2/-1 | 2 | -2 - (-1 x 2) | -2 - -2 | 0 | -2 = 2 x -1 + 0 | 0 = -2 - 2 x -1 |
