Faster/more reliable way to delete millions of rows?

Hello! I'm in the process of working on an independent study project for one of my professors at CSUF, and have been requested to import a huge database dump (>40,000,000 rows of data) and do some work with it. I'm attempting to use a delete where one of the columns doesn't equal zero,

delete from table
where column <> 0;

and it's taking forever, and I've been running into issues and having to restart the query. Is there a better way?

Thanks!
