Update usage of / operator to use math.div

[joshblack]

The / operator will be deprecated in Dart Sass 2.0.0 as pointed out in: #8069 (comment)

This issue tracks the updates needed in @carbon/styles to move away from the / operator to math.div as has been recommended in: https://sass-lang.com/documentation/breaking-changes/slash-div

Unfortunately, our current Sass targets include node-sass and I don't believe this is something we can address in our codebase today. it will, however, be addressed in our v11 release.

Just a heads-up that there's an automatic conversion tool that you could possibly use until the sources are generated in the new format (but you probably already knew about that)…

Another option is (reportedly) this if you want to keep compatibility with node-sass &/or older dart-sass implementations

Seems like what bootstrap ended up doing is temporarily replacing / with multiplication as another option 👀

I guess that is another option 😆
