    Question Question About Binary Division

    How would I divide these two binary numbers?

    100101/011011

    This is assuming I am on a 6bit 2's complement machine. I would understand how to do it if the first number were not negative. How do I approach this?

    Thank you!

    Why not negate the first number and then make the answer negative at the end?

    Edit: Although I did verify that the usual "subtract until you get 0" method works here as well; you subtract 011011 from 100101 a total of 111111 times to get to 0, for a quotient of 111111 = -1 which you would expect from -27/27.

    Is this how the computer would operate on this problem?

    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}
