[Tex/LaTex] How to get a “divide by” symbol with \usepackage{physics}

Question

I usually use \div to generate a divide-by symbol, but when using the physics package, \div gives a nabla followed by a dot ("period") instead.

Answer 1

In general, one should be able to store a symbol before it is overwritten by a package like in the following example:

\documentclass{article}

\let\olddiv\div
\usepackage{physics}

\begin{document}

$\div \quad \olddiv \quad \divisionsymbol$

\end{document}

Specific to physics, the package already does this using the macro \divisionsymbol.
