How can I prove that binary multiplication decision problem is solved in O(logn) space?

I can prove this if I use a NTM Turing Machine, but it is required to use a two-taped DTM, while taking into account only the space of the second "work tape"

    Can you provide an outline of how you would handle this using the NTM and where you get stuck moving to the DTM? Questions with context and shown-working tend to be better received and answered.

    When you say "NTM Turing Machine", does that mean "Non-deterministic Turing Machine Turing Machine"?
