Auto Paginate/Pagination Plugin or Code

I read that you can use the <!–nextpage–> code to paginate posts, but I am trying to automate this process.
I used the “Automatically Paginate Posts” plugin, which does automate pagination in posts, except that it destroys the cloud template styling. (In my case, the side content falls underneath the main post content.)
I also tried the “WP-Paginate” but not much progress in that.

Is there a plugin that automatically paginates posts that is compatible with the tagDiv Newspaper theme? Or is there some javascript code I can implement (and if so which file?) to do this?

Thank you!
