どう vs どうやって

どう is a general question word meaning "how," used to inquire about the state, condition, or opinion of something, such as このりょうり料理はどうですかきごう？ (How is this dish?) or どうおもいます思いますかきごう？ (What do you think?). It focuses on abstract or evaluative "how."

In contrast, どうやって specifically asks about the method or means of doing something, like どうやってこのきかい機械をつかいます使いますかきごう？ (How do you use this machine?) or どうやってここにきました来ましたかきごう？ (How did you get here?).
