ELI5 - how does the body decompose in a casket?

How does the body decompose in the casket? Does it eventually just become goop? Do the bacteria within multiply and eat you up?

Yes, the microbes on and in your body multiply and digest all the flesh, organs, etc.  The ossified parts of bone will stick around for a good long while, but given enough time, those will be broken down and digested too.
