I agree that just drilling on the mechanics of long division doesn't help. But, drilling the concepts can help. The point of the article is that instead of letting kids discover everything on their own and then feeling happy, teachers should direct their learning. In doing so, I would say they should drill the same concept repeatedly and ask questions that test both the ability to do the procedure and understand the concept. Anecdotally, this is how I taught my sister multiplication and how my friend tutored someone in calculus.
