In these chapters (as far as the operation of quotition division is concerned), the discovery of certain multiplication facts which can be used as ‘milestones’ in division has been emphasized. Thus, when the child knows that 8 × 23 = 184, he readily understands that 184 ÷ 23 = 8. He has also been discovering that his ‘milestones’ are valuable aids to the working out of divisions involving remainders. Thus, knowing that 8 × 23 = 184, he understands not only that 190 = 8 × 23 + 6 but also that 8 × 23 = 190 – 6 190 ÷ 23 = 8 with remainder 6 and

190 ÷ 8 = 23 with remainder 6

For an understanding of division, the value of basic multiplication facts in carrying out the operation must first be realized. When learning the procedure, pupils are asked to write down divisions in their multiplication form; that is, to discover the ‘milestones’ that will assist in each particular instance; for example: 1

86 ÷ 10 =

8 × 10 = 80 = 86 – 6

2 289 ÷ 17 =

172 = 289

3 569 ÷ 25 =

25 × 22 = 550 = 569 – 19

4 639 ÷ 32 =

20 × 32 = 640; hence 19 × 32 = 640 – 32; 19 × 32 = 608 = 639 – 31
