50 : 7 = 7 (ост. 1) ............... 7 * 7 + 1 = 49 + 1 = 50
67 : 7 = 9 (ост. 4) ................ 9 * 7 + 4 = 63 + 4 = 67
76 : 9 = 8 (ост. 4) ................ 8 * 9 + 4 = 72 + 4 = 76
8 : 9 = 0 (ост. 8) ................. 9 * 0 + 8 = 0 + 8 = 8
30 : 4 = 7 (ост. 2) ............... 7 * 4 + 2 = 28 + 2 = 30
