When I try to paste 8739297430300090 in a cell, it defaults to 8.7393E+15 on google Excel. I have done nothing different than previous cells

I am working on a spreadsheet for a business. I have been copying and pasting phone numbers, names, emails, and their ID numbers. This particular number, 8739297430300090 is defaulting to 8.7393E+15. I haven't asked for it, I don't see that I have done anything differently, I even tried a new cell, same thing.
