By long division method:

`7x-1 |21x^4+32x^3+2x^2-x+7| 3x^3`

`21x^4-3x^3`

(-)-----------------------------------------------

` 35x^3+2x^2-x+7| 5x^2`

`35x^3-5x^2`

(-)----------------------------------------------

`7x^2-x+7| x`

`7x^2-x`

(-)----------------------------------------------------

` 7`

The division yields, `(3x^3+5x^2+x)` as the quotient and `7` as the remainder.
