There isn't an option at the moment to display the current page over the total number of pages on the pages of the score. What you can do is go to Settings->Display Settings and change the "Page Slider Visibility" to "Always". The page slider will then always show you the page/numPages like you are wanting at the cost of having it take up some space on the screen. You can also enable "Always Show The Title Bar" which would accomplish the same thing.
