Hi, I have final round at all 3 MBBs coming up in the next two weeks and would like to make sure I'm as prepared as I can be.

I'm fairly confident in my quant skills, but **my only real insecurity remaining is divisions**. I'm just not good at it: I don't know a lot of shortcuts and for those divisions where no shortcuts apply, I have a really hard time doing the math.

For instance: 6,300,000 divided by 7,200. I just have absolutely no idea how to tackle this. My best try is to attempt long division, meaning the long and painful process of telling myself:

(1) Basically figure out how much is 630/72 and then add the zero's.

(2) Ok 72 doesn't fit 10 times in 630, how about 9? No neither, ok it fits 8 times.

(3) Ok how much is 72*8? It's 576, so 630-576 = 54.

(4) Ok let me make this 540 and see how much 72 fits into this, and I'll divide by 10 later.

(5) etc ...

Any advice at all please? How would you calculate 6,300,000 divided by 7,200, or any other large division of the kind?

A sincere thank you in advance!

Hi Vlad, thanks for responding. 1) I already use, 3) I forgot about but is very useful indeed. On 2), could you elaborate how you do the basic division technique? Do you use long division and write it out?
