In base 30, each digit position represents a power of 30: the rightmost digit counts individual ones, the next counts groups of 30, the next counts groups of 30×30, and so on — the same place-value idea as base 10, just with 30 distinct digits instead of ten.
Base 61 works the same way: the rightmost digit counts ones, the next counts groups of 61, the next counts groups of 61×61, and so on, using 61 distinct digits.
