You only need to know how to do synthetic division (ideally, synthetic...) and understand what the Remainder Theorem means. In your example, the remainder will be f(-4).
-4_____|____2____-3_____-45_____-54
_______|_________-8_____44______4
____________________________________
_______|____2____-11____-1______-50
See the remainder is -50.
