Content sharing queue works on the basic account. You can assign multiple time slots for each day for each account. To simplify this, see the image below.
As per the above image, consider the fact that 14 posts are in queue and the first post will share on Friday at 1:00 p.m.; the 2nd post will share on 10:00 p.m. while the 3rd post will share on Saturday at 3:30 p.m. If there are no posts in the queue after that, the slots in the schedule will remain unused.
