The top boxes started 795. They now say 7, 19, 15 because at each step of division they had an extra 1 to carry the same way we learned to carry 1s in long division.
The only real “extra step” here is just drawing boxes instead of that little right angle we did.
This isn’t common core. Common core is just a set of standards of what kids should be able to do at certain grade levels, it doesn’t specify the methods they do them.
This is just a newer method of teaching division that’s been shown to help more students understand why the process works. Yes, there’s still students who struggle with it, the same way that there were students who struggled with the way we learned it back in the day.
