LONG DIVISION (2 DIGITS)

               What is 18 ÷ 3 = ?                                                             T O

               Recall the table of 3 till we get 18.

               6 × 3 = 18                                                                       6
               So, 18 ÷ 3 = 6                                                              3   1 8

               This division can also be done as shown alongside.                            – 1  8

               This is called long division.                                                     0

                        4
               Divide  8 by 3.
                                                              4
               Here, the tens digit of the dividend ( 8) is greater than the divisor (3). So, we
               first divide this digit as shown below.

                                          T O

                                         1  6
                                          4

                                       3    8
                                         – 3       (Recall the table of 3; 1 × 3 = 3)
                                                                          4
                                          1  8     (Subtract 3 from  ; bring down 8)
                                           – 1  8  (Recall the table of 3; 6 × 3 = 18)

                                             0

                    4
               So,  8 ÷ 3 = 16

               Division with Remainder
                                 4
               Divide 53 by  .

                                          T O
                                         1  3

                                       4     5 3
                                                                             4
                                                                                           4
                                                                                      4
                                         –  4       (Recall the table of  ; 1 ×   =  )
                                                                4
                                          1  3      (Subtract  from 5; bring down 3)
                                                                             4
                                                                                      4
                                           – 1  2   (Recall the table of  ; 3 ×   = 12)
                                             1      (Stop the division when the
                                                    remainder is less than the divisor.)

                                             4
               So, if we divide 53 by   we get 13 as the quotient and 1 as the remainder.
