This is a red herring, IMHO.

In the decimal systems, you can easier divide by 2, 5,
you can easier divide by many powers of two, and all
powers of 16.

For arbitrary divisors, the decimal system seems to be
easier, as you would use the same division algorithm,
in both systems, however with different tables (dubbed
“multiplication table” or, less formally, “times table”)
that comprise 100 vs. 256 entries. Hence, the the hexa-
dekadic multiplication table should be 2½ times as hard
to learn, and memorize, as the decimal one.

Of course, a larger base needs less digits (on average)
for any given number; hence divisions for large numbers
in the decimal one; whether this will outweigh the larger
multiplication table to be used, is, I reckon, a matter
of taste. Somewhere, there must be an optimum: I cannot
imagine people to learn, and memorize, e. g., the 3600
entries of the multiplication table for base 60.

This whole deliberation is, of course, purely academic.
In real life, you will have to use the decimal system
as everybody else does, lest you wont be misunderstood.
