What's your process for removing search results from google?

Depends whose page it is. Your own site: noindex or delete the page, then the Removals tool in Search Console to speed it up. Someone else's site: ask them to take it down. Once it's gone from their site, use Google's outdated content tool so the old snippet disappears. If it's your phone number, address or similar, there's the Results about you tool for that. Google won't remove something just because it's negative.
