Antoine Pitrou commented on ARROW-9253:
---------------------------------------
We could use high-precision multiplication by reciprocal. Boost's int128_t
seems quite fast:

> [C++] Add vectorized "IntegersMultipleOf" to arrow/util/int_util.h

> There are various places where we check whether an array of integers are all
> a multiple of another number (e.g. a multiple of 86400000 milliseconds per
> day). It would be better to factor out this data check into a reusable
> function similar to the {{CheckIntegersInRange}} function
