Divide 478 by 16. use partial quotients

In partial quotients, it need several steps before it can  find the quotient.

Example : 
      16    |     478    |
                  - 320   |  20
                   158     |         
                   -144    | 9
                     12

Since 12 is less than 16, it now became a remainder

so the answer is 29 R 12

hope this helps
