Evaluates `self_i / other_i` for each element of an array instance with the respective element of the array `other`.

```{note}
If one or both of `self` and `other` have integer data types, the result is unspecified and thus implementation-dependent.

#### Special Cases

For floating-point operands, let `self` equal `x1` and `other` equal `x2`.
