Deal with series of steps (7)
I believe the answer is:
process
I believe this is a double definition.
'deal with' is the first definition.
(processing is a kind of dealing with)
'series of steps' is the second definition.
(I've seen this in another clue)
(Other definitions for process that I've seen before include "Advance ceremoniously" , "Method of operation" , "Series of steps achieving a particular end" , "The case" , "Deal with, action" .)
