Division

(3x^3+x^2+2x+4) /  (x-2)

            3x^2  + 7x  +16

x - 2  [ 3x^3 + x^2 + 2x + 4  ]

           3x^3 -6x^2

          ----------------------

                    7x^2  + 2x

                    7x^2 -14x

                   ---------------

                            16x + 4

                            16x -32

                           ------------

                                   36

So....the result is       3x^2 + 7x + 16  Remainder 36
