If you slightly modify it to 0. 0 1 2 3 4 5 6 7 8 9 00 01 02 03 04 05... then the number n padded with zeros to k digits can be found starting at position 10 *

If you slightly modify it to 0. 0 1 2 3 4 5 6 7 8 9 00 01 02 03 04 05... then the number n padded with zeros to k digits can be found starting at position 10 * floor(10^(k - 1) / 9) + k * n.
