Ruby on Rails return results in % or blocks of info

I have a web app on Ruby on rails with more than 20 million records and counting in a Postgres database. I have a page/controller that does some big time operations with this data so the user is waiting for more time that I would like.

Is there any way I can return data in blocks of info? I mean, I imagine the user seeing the first 10 rows and waiting for the next ones with a percentage bar that informs him how much is done (10% data returned for ex.)

I guess that with multiple ajax/json calls this could be done but I'm trying to avoid multiple calls.

By the way, I'm using Rails 3.2
