Skipping to learn long division by hand because you'll always have a calculator (or better a smartphone at hand) is like going to a gym with a forklift. It is faster to lift the weights, but it kinda defeats the purpose.
Learning to do long division by hand trains the mind. It prepares you to understand polynomial division. It teaches you the deep connection of division and subtraction. So, mastering it should be part of the curriculum. As soon as it is truly mastered, it should be allowed to use a calculator.
