5x*3 +6x +8 / x+2 = 5x*2 -10x +26
5x*3 +10x*2
______________
---- -10x*2 +6x
        -10x*2 -20x
        ------------
         ------ 26x +8
                     26x +52
                    ---------
                     ---- -44

7/2 = 3+1/2
From Mathematica Home Edition:
PolynomialQuotientRemainder[5 x^3 + 6 x + 8, x + 2, x] = {26 - 10 x + 5 x^2, -44}
 or$$5 x^2-10 x+26+\frac{-44}{x+2}\to 5 x^2-10 x+26-\frac{44}{x+2} $$
