Haraguchi started reciting numbers Friday morning, but lost his place around 16,000 (I hate it when that happens) and started over until he reached his current record. He didn't reach that mark until midnight on Saturday.
As expected, there are lots of sites devoted to the greatness of pi, which also is celebrated every March 14 (3/14...how cute). There's a pi research page that lets you search for any number string and see where and how often it appears in the first 200 million pi digits. If you'd like, you can see the first 100,000 digits. There was also a 1998 movie call Pi for whatever that's worth.
A supercomputer calculated pi to 1.24 trillionth decimal places in 2002, but the actual number doesn't have much usage past the first 10 places or so in normal activities.
Curious to see how you'd stack (or count) up to Haraguchi? Here are the first 1,000 pi decimal places...time to start remembering:
