        Division by a 2-digit number                                                    Fact-o-meter
        Let us divide 4385 by 16 and check the answer.                                The  dividend  cannot

        Hence, Quotient = 274, Remainder = 1                          2  7  4         be less  than  the

                                     = 16 × 274 + 1               –  3  2             the divisor. If it is not
                                                                                      so  then  check your
                                     = 4384 + 1                     1  1  8           division again.
                                                                  –  1  1  2
                                     = 4385                           6  5
                                     = Dividend.                      –  6  4
                                                                       1
                  Thus, the answer is correct.


              Let’s Attempt

        Example 1:  Divide 9437 by 26 and check your answer.                                      3  6  2

        Solution:      Quotient = 362, Remainder = 25                                      26   9  4  3  7
                       Check: Divisor × Quotient + Remainder                                  –  7  8

                                       = 26 × 362 + 25                                          1  6  3
                                                                                              –  1  5  6
                                       = 9412 + 25                                                7  7

                                       = 9437 = Dividend.                                         –  5  2
                       Here, Quotient = 362, Remainder = 25                                       2  5

        Example 2:  Divide 18735 by 31 and check your answer.
        Solution:      Quotient = 604, Remainder = 11                                        0  0  6  0  4
                       Check: Divisor × Quotient + Remainder                            31   1  8  7  3  5

                                       = 31 × 604 + 11                                     –  1  8  6

                                       = 18724 + 11                                              1  3  5
                                       = 18735 = Dividend                                      –  1  2  4
                                                                                                1  1
                       Thus, the answer is correct.
