Explicație pas cu pas:
36 : 9 = > 4
36 - 9 - 9 - 9 - 9 ( scadem pe 9 de 4 ori)
36 - 9 = > 27 - 9 => 18 - 9 = > 9 - 9 = > 0
21 : 3 = 7
21 - 3 - 3 - 3 - 3- 3- 3 - 3 ( scadem pe 3 de 7 ori)
21 - 3 = > 18 - 3 = > 15 - 3 = > 12 - 3 = > 9 - 3 = > 6 - 3 = > 3 - 3 = > 0
380 : 10 = 38
380 -10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10 ( scadem pe 10 de 38 ori )
66 : 11 = 6
66 - 11 - 11 - 11 - 11 - 11 -11 ( scadem pe 11 de 6 ori)
66 - 11 = > 55 - 11 = > 44 - 11 = > 33 - 11 => 22 - 11= > 11 - 11 = 0
