The production secretary, line producer, A.D., or another involved person will number your scenes once your script is going into production.
If you are working on revisions or a production draft and the scenes are already numbered, the question of how to handle renumbering is more complicated, and should be evaluated on a case-by-case basis. John August addresses a specific case in this blog post.
In multicam sitcom scripts, scenes generally are numbered (or lettered, more accurately), but if you are writing a spec episode, you should consult scripts for that specific TV show to see how it is handled.
