See the attached scans of handwritten pages I wrote in 1982 to approximate e (2.71828...) to 400+ decimal places on an HP-16C. It takes about 3.5 hours to run, plus the time to enter the 2 program halves and see the results 8 digits at a time. The results are that the fractional portion of e truncated to 404 digits is:
