You will get a BeforeNavigate and DocumentComplete event for the outer web page, as well as each frame. You know you're done when you get the DocumentComplete event for the outer webpage. You should be able to use the managed equivilent of IWebBrowser2::TopLevelContainer() to determine this.

Beware, however, the website itself can trigger more frame navigations anytime it wants, so you never know if a page is truly done forever. The best you can do is keep a count of all the BeforeNavigates you see and decrement the count when you get a DocumentComplete.

Edit: Here's the managed docs: TopLevelContainer.
