### Page numbering “<n> of <m>”

Finding the page number of the last page of a document, from within the document, is somewhat tricky. The lastpage package is therefore supplied to make life easy for us all; it defines a label `LastPage` whose number is right (after sufficiently many passes through LaTeX, of course). The memoir class also defines a “last page” label.

The documentation of the fancyhdr package spells out exactly how one might actually use this information to produce page numbering as suggested in the question.

`lastpage.sty`
