I have an equation in from of
a=VERYBIGSTUFF / VERYBIGSTUFF
And I would like to have a "verybig" forward slash in the middle of them. I don't like \frac mode, as I would like to have them left-to-right, not one above the other. I tried also changing the size of the "/" like \text{\LARGE $/$} but this gives a non centered slash, it goes upwards (as a different typography size would do, of course).
How can I insert that big forward slash?
[Something of an extended comment]
Lyx can handle a variety of math mode items, but where it cannot handle them you have to insert raw LaTeX code ('ERT'). Other than extending the Lyx binary, there is not much that can be done here. (Even then, there will still be limits to what Lyx can handle.)
Just resize the equation:
\documentclass[a4paper,twoside,twocolumn,final]{article}
\usepackage{graphicx}
\setlength\textwidth{42.5pc}
\setlength\columnsep{1.5pc}
\begin{document}
\texttt{\\columnwidth is \the\columnwidth}. We are going to see a wonderful equation, it extends to the other column and knows no limits:
\[
\resizebox{\columnwidth}{!}{$\displaystyle
\frac{k + l + m + n + p + q + r + t + u + v + w + x + y + z}{a + b + c + d + f + g + h + i + j + k + l + m + \frac{t + r + y + l + k + s}{\frac{small + characters }{are + fine}}}
$}
\]
\end{document}

It is also possible to put the equation into the brackets and then use the \middle/ instead of the regular slash.
So, for example, this equation:
would turn into this one:
Or if you do not need any visible brackets, you may use the "fake" brackets instead:
