Can someone help me understanding negative floor division?

Question

I noticed that negative floor division behaves different than the positive one. The point I noticed that was when I saw a code when - 11// 3 = - 4 instead of 3 as I expected. So I wrote a code to compare positive and negative floor division and it seems like there is indeed a difference. Can somebody help me understand this?

Answer 1

Yeah this I understand but shouldn't this be the same for positive and negative values? I mean if it's + oder - 4 I will divide through 3 it will be in both cases just fit in 1 time. For positive values this is true but for negative its 2.
