Integer division

[MarcusRainbow]

In Python, integer division is written //. For example 3 // 2 = 1. This also applies to floating point numbers, so 3.1 // 2.05 = 1

In Rust, there are two cases:

integer operands: just use the standard / operator.
float operands: we need to do floating point division and then floor. (The floating point numbers may not be within the representable range for integers.)
