Shared out in the manner indicated (8)
I believe the answer is:
assigned
'shared out' is the definition.
(assigning is a kind of sharing out)
I cannot understand how the remainder of the clue works.
(Other definitions for assigned that I've seen before include "Allotted or delegated" , "transferred" , "selected" , "Given a task" , "Appointed to a duty or task" .)
