When doing division, you will need to divide 165 by -5, in which the answer should be negative. Every 5 to 165 is equal to 1 quotient for the answer (Something like that XP) and so when you put all the 5's into 165, you will get 33, but the answer will be reflected from a positive to a negative since the answer should have a negative sign, making the answer to the question you put in, -33.
Hope this helped!
