Even Distribution

Or to do the full distribution ...

put Njobs div Ndrivers into tMin
put NJobs mod Ndrivers into tExtras

repeat with i = 1 to NDrivers
    if i <= tExtras then
       allocate tMin+1
      allocate tMin
   end if
end repeat

However, say your drivers are sorted alphabetically, then before long 
Andy will realise that he is being allocated more jobs that Zebedee. You 
could (sometimes) reverse the order of drivers - but then Mary loses out 
on jobs compared to both Andy and Zebedee. Or you could randomize the 
order of the drivers - but maybe they're also pre-sorted by location.

Instead, you want to even out the spread of extras across the drivers - 
so you need something like

repeat with i = 1 to Ndrivers
    if tExtras > (Ndrivers-i)/2 then
       allocate tMin+1
       subtract 1 from tExtras
      allocate tMin
   end if
end repeat

(which still has a slight bias towards giving jobs to Zebedee - but it's 
so slight it will take probably take him years to notice :-)
