Loadin content from php page

Loadin content from php page

Hi to all,

Newbie here :)

Well, i have a lagre php page containing a lot of divs.
Some functions take a lot of time in order to retrieve from db and then produce the html to be placed inside certain divs.
So what i want is to first load the page without loading the html that requires time, and after the page is loaded then produce the html. Its all in the same page, so i am bit confused.

I know i have to deal with the
  1.   $(document).ready(function()
but how can i first load some divs and then after this divs are loaded , afterwards load some other divs, all in the same page??

Thanks
