Lesson One hundred and thirty: Dividing With More Digits

The steps you follow in division are always the same, but in long problems you have to repeat them until you run out of numbers needing to be divided. 


           34 r5              1. DIVIDE  (How many times will 13 fit into 44?)
        +-------              2. MULTIPLY (3 x 13 = 39)
     13 | 447                 3. SUBTRACT (44 - 39 = 5)
          39                  4. BRING DOWN ( 7 )
         -----                5. DIVIDE (How many times will 13 fit into 57?)
           57                 6. MULTIPLY (4 x 13 = 52)
           52                 7. SUBTRACT (57-52=5)
          -----               8. REMAINDER ( 5 )
            5
Here's another example: 

           48 r3
        +--------
    15  | 723
          60
         -----
          123
          120
         -----
            3
