I'm self-taught, with 3 years' experience as a web developer.

Currently looking for a C# ASP.NET MVC development position within Chelmsford or London. I've been out of work for quite a while, so if you have an opening for a junior position, I'd still like to know. I just want to get back to work.

Would you consider 'deliberate learning' to be the same as 'active learning'?

Doesn't "you must pay the daily fee unless you are a subscriber to the service" imply they are mutually exclusive, rather than inclusive?

comment Why can/do we multiply all terms of a divisor with polynomial long division?
Ah, now that makes complete sense. I think that was probably what I couldn't understand all along. I went back over the 48 / 28 problem and realised that I'd get 1 + (20 / 28). Writing that as (4 * 10 + 8) / (2 * 10 + 8) gives 2 - (8 / 28). Then I realised they are the same answer, expressed differently. I can't thank you enough for your help.

Thank you, too, for your answer and again, I'm sorry it's taken such a long time for me to reply. I like that you've given me a completely different way to view the problem.

I can see that it rebalances, but I'd like to understand how someone developed this method, assuming this was created for real numbers first, and realising it would work like this algebraically. The result is the same but the rebalancing by having a negative remainder seems very different to the method for real numbers (at least to me).

Thank you for your answer. Sorry for my delayed reply but I've been snowed under since I asked my question. Whilst your answer has helped me, I've found this part confusing: Now think of 28 as 2*10+8. Same operations hold. I tried something similar so I feel like I'm on the right track, but it's not clicking for me. To keep it simple, I tried 48 / 28, written as (4 * 10 + 8) / (2 * 10 + 8). Working that problem gives me 2 - (8 / 2 * 10 + 8). I can see that it works, but I can also see that we've divided by more than what we originally had.

Simple and just what I needed. Thank you.
