Please help step by step if possible (I am a beginner)

- Header to numbered sections in the page header (1 / total number of pages ... the first section, 1 / total number of pages the other sections, ...)
- Footer, as all pages numbered in the footer (1 / total number of pages in document, 2 / the total number of pages in document ...)

my problem is when the section determine that the numbers go from 1, we are automatically in the footer to the same change, so it is not correct numbering in the footer.
