How To Make More Pages From One Article in WP?

I want to split some long articles into more pages, like this one is done (not in English, the button on the bottom says "Next page"). Is there any plugin for this?

I think its depend on your blog theme. Just check it with another theme

 

Yes,
<!--nextpage--> (you can insert it with this combination Alt+Shift+P)
code works

Only I need something more sofisticated, like I need to add a title of the next subpage on the previous one, like: Next page: Heart Disease Symptoms , and I would like that every writer would be able to edit this manually from the post draft.

 

Thanks @internetmarketingiq for sharing it. This technique really works for improving pageviews.
