Do it a lot like ordinary long division;
(-30+6y^3-28y+y^2) divided by (2y-5)
Put it the degrees in descending order (use.... to keep things lined up
:
..........................3y^2 + 8y + 6
.............---------------------
(2y-5)|6y^3 + y^2 - 28y - 30; choose a value, that, when mult by the divisor = the 1st term
..............6y^3 - 15y^2
...........---------------
...........................16y^2 - 28y
...........................16y^2 - 40y
...........................------------
.........................................12y - 30
.........................................12y - 30
........------------------------------------------
................................................0 remainder
