Let's perform the synthetic division
color(white)(aaaa)4color(white)(aaaaa)|color(white)(aaaa)1color(white)(aaaaaa)2color(white)(aaaaaa)5color(white)(aaaaa)6color(white)(aaaaaaa)-32
color(white)(aaaaaaaaaaaa)_________
color(white)(aaaa)color(white)(aaaaaaa)|color(white)(aaaa)color(white)(aaaaaa)4color(white)(aaaaaa)24color(white)(aaaa)116color(white)(aaaaaa)488
color(white)(aaaaaaaaaaaa)________
color(white)(aaaa)color(white)(aaaaaaa)|color(white)(aaaa)1color(white)(aaaaa)6color(white)(aaaaaa)29color(white)(aaaa)122color(white)(aaaaaa)color(red)(456)
(x^4+2x^3+5x^2+6x-32)/(x-4)=(x^3+6x^2+29x+122)+(456)/(x-4)
The remainder is =456 and the quotient is =x^3+6x^2+29x+122
