Create random teams for assignment type "team upload" following specific rules.

example:

total exercise members : 9 members
total number of teams to create (defined via form): 4 groups
number of users per team --> 9 / 4 = 2 users
users to spread over groups --> 9 % 4 = 1 user
final teams: 3 teams of 2 users and 1 team of 3 users.
