I see the problem in my case anyways I failed to see what was going on in this table I did not realize it was a series of steps as decried in the article but thought it was list of various fractions being computed I did not realize that each row was a series of iterative steps Or perhaps gavin green your example I was ready to understand the table I still like how you presented the process It just clicked for me Very easy to understand I dont think you could make it any clearer than how you have presented it  I especially like that the decimal numbers are shown approaching the final result     is the fraction expansion right
