Divide one input by another

### User story
As an analytical code developer, I want a function that divides one number by another, so that I can practice using Git.

### Definition of done
- [ ] Runs without error
- [ ] Fully meets the user requirements
- [ ] Documented using a [docstring for python](https://peps.python.org/pep-0257/) or [roxygen2 comment for R](https://cran.r-project.org/web/packages/roxygen2/vignettes/roxygen2.html)
- [ ] Peer reviewed and updated if needed

No file, test, or entry point is named, so first identify the repository's intended language and location for the exercise. Add a function that divides one input by another, document it with the applicable Python docstring or R roxygen2 comment, run it without error, and have it peer reviewed.
