Help please! Creating a process

Regular Visitor
Hello guys, i would like to ask for your help pleaseee😊

I need to create a proccess of seating people in 5 different areas according to a system. For example, the user clicks on a button and he will Be assigned a seat. The system in the background should assign 5 areas by starting to fill each area to 50% of its capacity (full capacity is 6 seats)then start to assign the users one by one in a rotation process.

Thank you for your time❤️
