Many shopping sites have indicators of how far you are through the
buying process ("Step 2 of 4"), and online surveys often have progress
bars indicating the position in the survey.

Typically these are static to the page (as in, making progress and
seeing the indicator move involves submitting a form and displaying the
next page in the sequence), but so far as I can see from the spec
<progress> can be used in these situations; it isn't restricted to use
on a single page where it is updated dynamically.
