The correct spelling of the phrase "does in to" is actually "does into". The word "does" is the third person singular present form of the verb "do" and is pronounced as /dʌz/. When combined with the preposition "into", it forms a phrasal verb meaning "to enter" or "to go inside". The word "into" is pronounced as /ˈɪntu/ and is spelled with one 'o'. Therefore, the correct way to spell the phrase is "does into", not "does in to".
