Meanings

1

usually written using kana alone

Standard interrogative adverb asking about manner or method. Used in both formal and informal contexts.

どう
どう is a casual, everyday way to ask 'how,' while どのように is more formal and explicit, often used in writing or polite speech.
どうやってN5
どうやって specifically asks about the method or means of doing something, whereas どのように can also ask about a state or manner more broadly.
ハウ
どのように is a more formal, fully natural Japanese phrase for “in what way,” whereas ハウ is a borrowed transcription of English “how” rarely used in real sentences.

どんなにN3
どんなに asks about degree or intensity ('how much'), while どのように asks about manner or method ('in what way'), so they are not interchangeable despite the similar sound.

Compound of どの (interrogative prenominal) + ように (adverbial form of ようだ, 'like, in the manner of').
