The best way to write this code? Jquery

Ive got an array which I am doing a few things, but now I am trying to split it between "pages" (more like slides).

I am going through it with a method .each()

, calling this long bit of code to put the information on the correct page (only 5 elements per page, at least for now).

Is there a way to simplify this code?

Ideally, this could go on indefinitely:

if (index > 0 && index <= 5) {
    var page = $('#librarian-page-gallery-1');
} else if (index > 5 && index <= 10) {
    var page = $('#librarian-page-gallery-2');
} else if (index > 10 && index <= 15) {
    var page = $('#librarian-page-gallery-3');
} else if (index > 15 && index <= 20) {
    var page = $('#librarian-page-gallery-4');
} else if (index > 20 && index <= 25) {
    var page = $('#librarian-page-gallery-5');
} else if (index > 25 && index <= 30) {
    var page = $('#librarian-page-gallery-6');
} else if (index > 30 && index <= 35) {
    var page = $('#librarian-page-gallery-7');
} else if (index > 35 && index <= 40) {
    var page = $('#librarian-page-gallery-8');
} else if (index > 45 && index <= 50) {
    var page = $('#librarian-page-gallery-9');
}

For example:

var page = $('#librarian-page-gallery-' + Math.ceil(index/5));

Explanation:

   index/5 builds a float number :
         1 -> 0.2
         4 -> 0.8
         5 -> 1
         6 -> 1.2

   and Math.ceil returns the nearest greater or equal integer :
         0.2 -> 1
         0.8 -> 1
         1   -> 1
         1.2 -> 2
