10010
101__
1000 < shift, 3rd operation

One way to do division (and there may be others), is to repeatedly subtract, counting the subtractions. When the result goes negative, don't count the final subtraction, but put it back and shift the register, subtract repeatedly......
There are other algortithms but that is one of the simplest to understand.
