I had to relearn long division recently, because I just started division with polynomials in my math class. I realized that I didn't quite understand the whole process of long division. I can follow the steps that the teacher sets out, I just don't really understand the steps, why you use this specific method. I'm not debatingit or anything, I'm just wondering about the reasoning behind the steps, I guess another way to describe what I'm looking for would be how someone would come up with the idea of long division, and understand why you take all of the steps. This is probably really simple, but I just don't really understand it. He's an example to aid this explanation: 210/7.(adsbygoogle = window.adsbygoogle || []).push({});

I used a fairly simple example just so that I can get the important points. If someone could explain the process of long dividing this, as well as the reasoning, I'd be greatful. Note, I know how to long divide it, I just understand the method.

I'll get to the harder polynomial confusion after this has been sorted out. Thanks in advance.
