Create a function

[slava1857]

Please help create a function that will create additional column "remainder". This solution should calculate the remainder according to the logic illustrated in our provided screenshot, where each successive row reduces the quantity accordingly. I would be very grateful for your help (ChatGPT and Copilot can't help). Thanks
