Dividing whole numbers with a dividend not exceeding 1 000 000 000

Dividing whole numbers with a dividend not exceeding 1 000 000 000

The steps for dividing whole numbers are the same as those you learnt in Standard Six. Division of large numbers becomes easier when the long division method is used.

Example 1

$43\,706\,250 \div 225 = ?$

Solution

Divide by using the long division method as follows:

    194250
225)43706250
   -225
    2120
   -2025
      956
     -900
      562
     -450
      1125
     -1125
         0

Therefore, $43\,706\,250 \div 225 = 194\,250$.

Example 2

$126\,947\,364 \div 93\,619 = ?$

Solution

Divide by using the long division method as follows:

     1356
93619)126947364
    -93619
     333283
    -280857
      524266
     -468095
       561714
      -561714
            0

Therefore, $126\,947\,364 \div 93\,619 = 1\,356$.

Example 3

$24\,463\,239 \div 354 = ?$

Solution

Divide by using the long division method as follows:

    69105
354)24463239
   -2124
    3223
   -3186
      372
     -354
      183
      -000
      1839
     -1770
        69

Therefore, $24\,463\,239 \div 354 = 69\,105$ remainder $69$.
