IMHO. With calculators introduced, there is zero add in you learning long division. Worse than zero, you could have done something better with your time. ChatGPT is a calculator for all subjects. People have a hard time letting that sink in.
Long (or short—screw long division, with its transcription error opportunities and huge amounts of paper-space used) division is a good exercise to cement the notion of place value, that happens to also teach you how to divide by hand for when it's occasionally more convenient than finding a phone/computer/calculator.
AI is a calculator for all subjects, ChatGPT is not that advanced.
I still bet someone like you could pass any university exam in any subject with access to the ChatGPT app. Without any prep time. At that point it’s good enough.
