Is there a way to produce this division symbol? ÷

The term \div gives an error of Missing $ inserted.

is not working either.

I guess you have not tried $\div$, correct? –  Werner Apr 10 '13 at 23:41

\div is a mathematical symbol, so it should be inside a math formula: $6\div 3=2$ should work. If you want to use it in text, do \usepackage{textcomp} and use \textdiv. –  egreg Apr 10 '13 at 23:46
    
No, I hadn't tried with dollar signs or with the textcomp package. Thank you all so very much -- greatly appreciated! –  lawlist Apr 11 '13 at 3:17

Werner's and egreg's comments are correct: you should still use \div, but inside of math mode.

So: $6 \div 3 = 2$.

$6 \div 3 = 2$

@lawlist: your upvote (and check if this the answer you adopt) are thanks enough. –  Matthew Leingang Apr 11 '13 at 3:19

The questioner said: Is there a way to produce this division symbol? ÷

And I said:

With PSTricks

enter image description here

\documentclass[pstricks,border=3pt]{standalone}

\begin{document}
\begin{pspicture}(4,4)
    \psline[linewidth=10pt](0,2)(4,2)
    \pscircle*(2,0.75){15pt}
    \pscircle*(2,3.25){15pt}
\end{pspicture}
\end{document}

With TikZ

\documentclass[tikz,border=3pt]{standalone}

\begin{document}
\begin{tikzpicture}(4,4)
    \draw[line width=10pt,fill=black] 
        (0,2) -- (4,2)
        (2,0.75) circle (15pt)
        (2,3.25) circle (15pt);
\end{tikzpicture}
\end{document}

Miscellaneous

If you need a fancier div symbol...

enter image description here

\documentclass[pstricks,border=3pt]{standalone}
\usepackage{graphicx}
\makeatletter
\pstVerb{/ptcm {\pst@number\psunit\space div} bind def}
\makeatother
\SpecialCoor
\begin{document}
\begin{pspicture}(4,4)
\psclip
{
    \pscustom[dimen=middle]
    {
    \psframe[linewidth=10pt](!0 2 5 ptcm sub)(!4 2 5 ptcm add)
    \moveto(!2 15 ptcm add 0.75)
    \pscircle(2,0.75){15pt}
    \moveto(!2 15 ptcm add 3.25)
    \pscircle(2,3.25){15pt}
    }
}
    \rput(2,2){\includegraphics[width=4cm]{example-grid-100x100pt}}
\endpsclip
\end{pspicture}
\end{document}

It seems gratuitous to use TikZ or PSTricks to recreate a symbol that is in the basic set of math fonts. I can't think of any reason to adopt this answer over just \div, and worse, it might intimidate a novice user. (As I make this comment I see someone else has already downvoted.) –  Matthew Leingang Apr 11 '13 at 1:02
    
@MatthewLeingang: It depends on the context of use that has not been clearly defined in the question. –  In PSTricks we trust Apr 11 '13 at 1:14
    
Can you provide a use case where the TikZ/PSTricks method is preferable? –  Matthew Leingang Apr 11 '13 at 1:17
    
It's always nice to have a large bag of tricks, and also to see what is within the realm of possibilities. Thank you all so very much. –  lawlist Apr 11 '13 at 3:16
