Computer architecture organization

I used division algorithms by Stallings, Mano, Zaky etc. But I cannot get correct solution for all numbers in 2's complement form e.g. (-5) /( +1) with -5 represented as 1011 in 2's complement representation.
The algorithms work for only some numbers like -8/+3.
Can you help me please.
Thanks
