Most decaf is 99.9% caffine free. Alot of companies remove the caffine and sell it to soft drink companies.
The most commen way of decaffinating coffee is through methylene chloride. The green coffee beans are exposed to the methylene chloride, which then attaches itself to the caffine. The green beans are then briefly roasted (just long enough to get rid of the caffine/methylene chloride). Another method is call "Swiss Water Process". This process involves soaking the beans in water.
Either process will cause some loss of flavor, which is one of the reasons that coffee folk generally shy away from decaf.
