              example 2: Find the quotient and remainder for the following and check the answer.
                    (a)  504084 ÷ 6                                  (b)  621575 ÷ 25

              Solution:          8 4 0 1 4       Q     Step 1:  Since 5 < 6, we divide 2-digit number 50 by 6.
                    (a)     6   5 0 4 0 8 4                     6 × 8 = 48 is the maximum possible  product
                             –  4 8                             obtained  < 50.  Subtract 48 from 50 and  bring
                                  2 4                           down 4.
                               –  2 4
                                      0 8              Step 2:  24 is the new dividend. Here, 6 × 4 = 24 is the
                                   –     6                      maximum possible product obtained.
                                         2 4                     Subtract 24 from 24 and bring down 0.
                                      –  2 4
                                           0     R     Step 3:  Since 0 < 6, put 0 in quotient and bring down 8.
                                                                Now, 08 is the new partial dividend. Here, 6 × 1 =
                                                                6 is the maximum possible product < 8. Subtract
                                                                6 from 8 and bring down 4.
                                                       Step 4:  24 is the new dividend. Here, 6 × 4 = 24.  Now,
                                                                nothing  is  left  and  no number  is  left  to bring

                                                                down. So, stop.
                            Checking:                  Thus, Quotient = 84014 and Remainder = 0

                            Quotient × Divisor + Remainder = Dividend
                            84014 × 6 + 0 = 504084 + 0 = 504084. The division is correct.


                    (b)            2 4 8 6 3      Q    Step 1:  62 > 25. So, divide 62 by 25. 25 × 2 = 50 is the
                            25   6 2 1 5 7 5                    maximum possible product obtained < 62.
                              –  5 0                             Subtract 50 from 62 and bring down 1.

                                 1 2 1                 Step 2:  121 is the new dividend. Here, 25 × 4 = 100 is
                              –  1 0 0                          the maximum possible product obtained < 121.
                                   2 1 5                         Subtract 100 from 121 and bring down 5.
                                 –  2 0 0              Step 3:  215 is the new partial dividend. Here, 25 × 8 =

                                     1 5 7                      200 is the maximum possible product < 215.
                                   –  1 5 0                      Subtract 200 from 215 and bring down 7.
                                          7 5
                                        –  7 5         Step 4:  157 is the new dividend. Here, 25 × 6 = 150 < 157.
                                             0     R              Subtract 150 from 157 and bring down 5.
                                                       Step 5:  75 is the new dividend. Here, 25 × 3 = 75 = 75.

                                                                   Subtract 75 from  75.  Nothing  is left and  no
                                                                 number is left to bring down.
                                                       Thus, Quotient = 24863 and Remainder = 0
                            Checking:
                            Quotient × Divisor + Remainder = Dividend

                            24863 × 25 + 0 = 621575 + 0 = 621575. The division is correct.
