How to do manual division?

So, could you walk us through the steps of manual division, please? I understand it's a fundamental math skill, but I'm struggling to grasp the concept. Do we start by estimating the quotient, or do we dive straight into dividing the divisor into the dividend? Are there any specific rules or strategies that we should keep in mind to make the process smoother? I'd really appreciate it if you could break it down for me, step-by-step, in a way that's easy to understand.
