how to process time taking request in laravel?

I am trying to read data from excel file and and then store it in database. but there is problem . sometimes file has a lot of data nearly 20000 records. when I try to process that request with that much data it process for 2 to 3 minutes and enter around 13000 record in database and after that request got failed. here is what i am doing . this process gets completed in five functions every functions has it own job. Now, I think I should do it by queue but i have no idea how it will work because I am returning some thing from every function which won't work in queue and there is also global array in my controller.

here is my controller. I think you don't need to read all the functions one by one just give me idea how I can achieve my goal

    //global array variable declaration for import delivery Zone
    protected $createdDeliveryZones;
    protected $updatedDeliveryZones;
