19 : 8 = 2 r 3
190 : 80 = 2 r 3
163 : 8 = 20 r 3
1630 : 80 = 20 r 3
1030 : 500 = 2 r 30

Możesz dla pewności sprawdzić działania mnożeniem:
19 : 8 = 2 r 3, bo 2 ∙ 8 + 3 = 19
190 : 80 = 2 r 30, bo 2 ∙ 8 + 30 = 190
163 : 8 = 20 r 3, , bo 20 ∙ 8 + 3 = 163
1630 : 80 = 20 r 30, bo 20 ∙ 80 + 30 = 1630
1030 : 500 = 2 r 30, bo 2 ∙ 500 + 30 = 1030
13 : 5 = 2 r 3, bo 2 ∙ 5 + 3 = 13
10030 : 500 = 20 r 30, bo 20 ∙ 50 + 30 = 10030
1003 : 50 = 20 r 3, bo 20 ∙ 50 + 3 = 1003
