Originates from a bar in New York during the time of prohibition. The bar was located at 86 Something Street. Whenever the cops were coming, everyone was told to get out of 86 asap. The term evolved and nowadays means "to get rid of s.th./s.o., to kick s.th./s.o. out" etc.

Meaning to eject or debar from premises, to reject or abandon was/is an expression used by waiters and bartenders indicating that the supply of an item was exhausted or that a customer was not to be served.
I’ve heard mainly among restaurant workers. It seems to mean either that the restaurant is out of something (‘we’re eighty-six on flounder’) or, less often, that something should be gotten rid of (‘eighty-six that monkey—the health department is outside’).
And as Racko mention I also read that it originated at a New York City, Chumley’s, located at 86 Bedford Street, during Prohibition, when a raid was imminent, a cop on the take would call and warn the proprietor to ‘eighty-six it’: hide the booze and get the customers out.

I drank at Chumley's the night of the blackout last August... they had flashlights ducktaped to the ceiling and candles everywhere... everyone was ignoring the smoking ban. They had 3 beer taps left.. served until they were empty. Didn't have enough cash because of no ATM's... they gave me 2 rounds for free. It was great fun!
