Short answer first: I can cite the exact NSA/CIA Venona PDFs and the pages that discuss the one-time-pad method, the key-group-in-the-clear discovery, and which releases contain the published translations. However, after searching the public Venona declassification releases I could not find a literal scanned worksheet image in the public PDFs that shows both (a) the ciphertext 5-digit groups as printed on the original intercept and (b) the reused pad additive fragments (the worksheet “depth” fragments) together with the hand written digit-by-digit subtraction used by the original Arlington Hall analysts. Those internal worksheets and working pages are not present in the public monograph and translation releases I reviewed. Because that primary worksheet is not included in the publicly released PDFs, I cannot honestly produce an exact, verbatim end-to-end transcription of the original analyst’s handwritten arithmetic from those particular public files.

Below I give: 1) precise PDF references and the pages/sections that cover the relevant VENONA material, with citations; 2) an explanation of what the public releases do and do not publish (including which items are present in the translations); and 3) a fully worked, faithful demonstration of the exact digit arithmetic (mod 10) using a representative Venona ciphertext group and a pad fragment (clearly marked as a reconstruction because the original internal worksheet is not published). If you still want me to try to reconstruct the same exact message using a plausible pad fragment labeled for teaching (not as a claim to be the original worksheet), I include that demonstration at the end.
