In base 57, each digit position represents a power of 57: the rightmost digit counts individual ones, the next counts groups of 57, the next counts groups of 57×57, and so on — the same place-value idea as base 10, just with 57 distinct digits instead of ten.
Base 9 works the same way: the rightmost digit counts ones, the next counts groups of 9, the next counts groups of 9×9, and so on, using 9 distinct digits.
