I would go with `divideBy(int|float|self $divisor): self|int|float`
where the argument type defines the return type:
* `divideBy(int|float $divisor): self`
* `divideBy(self $divisor): int|float`
PHP doesn't support “method overloading” and that suggestion requires
method overloading. At least in spirit: It would require special -
static-analysis only - definitions for this signature to make sense to a
developer. With the “Deprecate functions with overloaded signatures” RFC
(https://wiki.php.net/rfc/deprecate_functions_with_overloaded_signatures)
we have specifically deprecated the use of overloaded signatures.
About integer division - I don't think this is the usual case so I
would keep that separate (for later) just like `$int / $int =
int|float` is the usual case and integer division `intdiv(): int` needs
to be handled more explicitly is needed.
“Integer division“ as you call it is the natural inverse of
multiplication. I don't think breaking up a Duration into multiple parts
of equal length is something unusual. Looking at the other languages we
took inspiration from, it's also the only division operation that Java
supports.
