The best and most expensive process is the Swiss water process.
It removes about 90% of the caffeine.
Always buy "Swiss Process Decaf".

decafination is a facinating process where they subject the coffee beens to carbon dioxide or oxygen in supercritical fluid state which absorbes the caffeen. There is a chance that it does not absorb out all of the caffeen, but it takes most of it...I dont have a percentage for you because it varies.

Decaf coffee is 99.9 decaf.

That is true. I'm not sure what the percentage is, certainly not enough to get worked up about.
