Paging a Node

I feel like a dummy as this seems like an easy thing to do, but I can't figure it out. Maybe I'm using the wrong search terms to find help. Anyway, I have a content type for instructional articles / tutorials on my site. Most entries / created nodes are short enough to pull up in full. However, some are quite lengthy. For the lengthy ones I'd like to have the node / page only display a certain length and then have a next / previous option with pages listed. Is there a way to do this? and can it be done without micromanaging each node? By this I mean someway to state that if the node is say greater than 1500 words, divide it up into 750 word chunks? I'm trying to avoid entering a single article over multiple nodes. Thanks!
