In my sector of the business world in the US, every corporation pays for Office 365 for their employees. I don't know a single corporation that uses Google Docs.
Everywhere I've worked has been Google Docs. Usually there is a process on the side that if you really, truly, need MS office specifically they can get you a copy, mostly for people in certain parts of finance who do specifically insist on Excel, but Google Docs has been the standard for like a decade now.
