Is there any way to stop VisualEditor from automatically adding the <nowiki> tags. For example if I want to type <div> Something </div> it changes it to <nowiki><div></nowiki>Something <nowiki></div></nowiki>

No. VisualEditor is a visual editor and is not appropriate for manually inserting raw HTML. For that, use the wikitext editing mode.
