How to use regexp to replace 5 found element and not all?

Question

Regular Expressions

I need to insert links on pages on many sites, and I want to automatically insert my link after every fifth " " on the page using regular expressions (that is, insert one link on the page that will go after 5 found by the regular expression " "). I was told that with the help of regular expressions this is possible. Can you help in this matter? </a></a>
