content in Div container not responsive

I am not a web dev guy. This is my first project and I need help in this. I am targeting this container which looks absolutely fine in PC, but the digits and heading just flows out of it in the Mobile(or when the digits get too large.) I just need help to make it a little more responsive and make it all bounded by the container.(size should remain absolute wrt the screen size and the components within it should remain relative wrt to the purple box. So can you please guide me. Thanks Here's the code: https://drive.google.com/file/d/1hd0JnnU0Z4rd3H3_P_9utPzZ37j3t5Cr/view?usp=sharing
