How to separate address now in 1 cell into 4 cells

Can someone help me break complete address, all in 1 cell, into Address, City, State and Zip into separate cells ? Each value is separated by a comma, except for the 5 digit zip code at the end that only has a space separating the zip from the state.

SAMPLE ADDRESS:

1387 W. Francis St., Ontario, Ca. 91762

Thanks in advance.
