Example 1:
43 ÷ 9 = 4, remainder = 7
quick remainder: 4 + 3 = 7
Example 2:
28 ÷ 9 = 3, remainder = 1
quick remainder: 2 + 8 = 10 ?
If the addition is ? 9, cast out the 9s, until it is lest than 9.
10 – 9 = 1
Example 3:
2345 ÷ 9 = 260, remainder = 5
quick remainder: 2 + 3 + 4 + 5 = 14
14 – 9 = 5
Example 4:
4489 ÷ 9 = 498, remainder = 7
quick remainder: 4 + 4 + 8 + 9 = 25
25 – 9 = 16
16 – 9 = 7
erm... tough.. haha

00000............000000588235294117647 is other number
Initial steps!
00000............000000588235294117646(one less than factor)
99999............999999411764705882353(Vertical sum is 9)
