Base 5 to Base 37

Base 5

In base 5, each digit position represents a power of 5: the rightmost digit counts individual ones, the next counts groups of 5, the next counts groups of 5×5, and so on — the same place-value idea as base 10, just with 5 distinct digits instead of ten.

Base 37

Base 37 works the same way: the rightmost digit counts ones, the next counts groups of 37, the next counts groups of 37×37, and so on, using 37 distinct digits.
