[ASK] Pagination Plugin for a Page

Hello,

I have a single page that contain many text and image (testimonial page). After 5 days, there’s so many testimonial I’ve inserted there. So the page became very long from top to bottom.
Now I want to make a pagination of this content, so I can set a limit (example: 5) for each content. So the content not become long again.
Is there any plugin to do this?
I already search and install some pagination plugin but it didn’t work.

Sorry for my bad English
