How do I extract this using regex?

I got a log containing "Step"-values in order: Step=11001 , Step=11018 , Step=12302 , Step=12319 , Step=12800 , Step=12805 , Step=12806 , Step=12801 , Step=12802 , Step=12305 , Step=11006 , Step=11001 , Step=11018 , Step=12304 , Step=12319 , Step=12804 , Step=12816 , Step=12311 , Step=15041 , Step=15004 , Step=15013 , Step=24432 , Step=24416 , Step=22037 , Step=15044 , Step=12312 , Step=12305 , Step=11006 , Step=11001 , Step=11018 , Step=12304 , Step=12306 , Step=11503 , Step=24703 , Step=24702 , Step=15035 , Step=15042 , Step=15036 , Step=15004 , Step=15016 , How can I extract fields from this? End result should be that each Step has its own field (Step1, Step2) and so on
