Tracking issue for div_duration

[newpavlov]

Rust PR: #62756

This feature adds the following methods to Duration:

• div_duration_f64(self, rhs: Duration) -> f64
• div_duration_f32(self, rhs: Duration) -> f32

Anything in particular holding up the stabilization here? The implementation is trivial and docs lgtm.

[Demi-Marie]

I would like to add methods that return an exact u128, but that can wait.

[KodrAus]

These methods are a little odd, but seem reasonable to me following the example given: #62756 (comment)

[Rua]

Given how straightforward these methods are, I don't think there's any problem stabilising them?

[KodrAus]

They're straightforward in implementation, but conceptually tricky at a glance. I think the docs will need some fleshing out before stabilizing but I don't have any other concerns if somebody wants to write a PR!
