Code:

x^2 + 2x + 1
_____________________
x + 2 ) x^3 + 4x^2 + 5x + 2
x^3 + 2x^2
------------
2x^2 + 5x
2x^2 + 4x
----------
x + 2
x + 2
=====

Synthetic division:

x^3 + 4x^2 +5x +2 divided by (x+2). Use -2 as divisor in synthetic division.

Code:

___________________
-2| 1 4 5 2
-2 -4 -2
___________________
1 2 1 0 (remainder)
Quotient = x^2 + 2x + 1
