According to your explanations I assume that the quotient reads:

Use long division:Code:`(z-1)(2a-12)`

z^4-2z^3+az^2-8z+8)÷(z^1-2z+2) = z^2+(a-2) + -----------

z^2-2z+2

-(z^4-2z^3+2z^2)

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

(a-2)z^2-8z+8

-((a-2)z^2-2(a-2)z+2(a-2)

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

-12z+2az-2a+12

And, specifically, subtracting from gives
