Binary  Division

Similar  to multiplication  division can be seen  multiple  subtractions.  For example  if we have to divide 9 by 4  we can subtract 4 ,2,  times  until is is left  with an number  less than  4, i ,e then 2 will be the  quotient and 1 will be the  remainder. Actually this  concept is used in  microprocessor for  division. Followings  example  shows  a simple  binary  division.

Example:  Divide   1101102 by 1012

Solution  :   divisor         10) 110110 (  1010

                                             101

                                                  111

                                                  101

                                                      100

Important  : multiplication is multiple additions and  division  is multiple sub tractions. And  as we know  that subtraction is  done by  addition  using 2 complement method. So the  division can be  done by  addition. Hence  a single  digital circuit of an adder can perform all these basic  operations of  additions  subtraction  multiplications and division.
