Automatically create pages in a post based on number of words

Can Wordpress automatically paginate large amounts of content?

A user wants to enter a document that is 3000 words long. They just want to paste this into the_content via the cms. Can Wordpress then automatically paginate that into separate pages that are say 300 words long?

Or would it have to be done manually? Where they separate the content into 10 separate pages?
