Ok so if the first pass is: 65 - (0*1664117991)

Would the second pass be: 66 - (65*1664117991)?

If so, then my output on the second pass would be a huge number.

And once I do each pass, am I adding up the numbers then? I've been scribbling on paper like you said for the last 10 mins trying to figure this out x_x ..sorry.
