Here's what I got:

(3x^4-5x^3-20x-5)/ (x^2+x+3)
=
3x^2 - 8x - 1 + (-2+5x)/(3+x+x^2)

Check the work, and then can you pick out the quotient and remainder?

It is long division. It's easier if you put 0x^2 into the dividend, as a placeholder between the -5x^3 and -20x.

I agree with eharley

Quotient: 3x^2 - 8x - 1
Remainder: 5x - 2
