From the given
(4z^4-11z^3+27z^2-39z-25)/(z^2-z+6)4z4−11z3+27z2−39z−25z2−z+6
You can see that the terms are arranged from highest degree to the lowest degree already. So we can divide at right away at once
" " " " " " " " underline(+4z^2-7z-4" " " " " " " " " " " " )
z^2-z+6|~4z^4-11z^3+27z^2-39z-25
" " " " " " " " underline(+4z^4-4z^3+24z^2" " " " " " " " " " )
" " " " " " " " " " " " ""-7z^3+3z^2-39z-25" " " " " " " " " " " "
" " " " " " " " " " " " underline(-7z^3+7z^2-42z" " " " " " " " )
" " " " " " " " " " " " " " " " " "-4z^2+3z-25" " " " " " " " " " " "
" " " " " " " " " " " " " " " " " " underline(-4z^2+4z-24" " " " " " " " )

Write the answer this way
"Dividend"/"Divisor"="Quotient"+("Remainder")/("Divisor")
(4z^4-11z^3+27z^2-39z-25)/(z^2-z+6)=4z^2-7z-4-(z+1)/(z^2-z+6)
God bless....I hope the explanation is useful.
