Is it possible to remove all<div> tags?

The problem is that, sometimes when people copy paste text from web or word inside ck editor - the html markup gets pasted too, and it can mess with the layout, when the text is being displayed on a page.
Lets say when you view the source and find some unwanted div tags, you remove them manually, but forget to remove one closing </div> ... - that will destroy your layout.
Is there a way to tell ck editor to remove all opening and closing <div> tags?

Thanks
