parcel out

verb

To divide into portions or chunks; to ration.
“It's a large job, but if we parcel it out among several people over several weeks, it shouldn't be too difficult.”
To assign.
“Jem parceled out our roles: I was Mrs. Radley, and all I had to do was come out and sweep the porch. Dill was old Mr. Radley: he walked up and down the sidewalk and coughed when Jem spoke to him. Jem, naturally, was Boo: he went under the front steps and shrieked and howled from time to time.”
