SASS moving to math.div and Minima is using deprecated division

[BillRaymond]

When I run bundle exec jekyll build --verbose, I receive the following warnings. There are several areas in the Minima theme's SASS files where math.div should be used instead of a / (divided by slash).

Here is the portion of my verbose output that displays the warnings:

  Rendering Markup: assets/main.scss
Deprecation Warning: Using / for division outside of calc() is deprecated and will be removed in Dart Sass 2.0.0.

Recommendation: math.div($spacing-unit, 2) or calc($spacing-unit / 2)

@BillRaymond Does math.div work on older stylesheets? If yes, feel free to submit a pull request for this.
