Default Re: Divide one big number by another big number (in head)

I wouldn't even try getting the correct answer
I would round to workable numbers and get a close-ish estimate.
678,242 : 680,000
98,724,622 : 100,000,000

680,000 / 100,000,000
68 / 10,000 -> Bring 68 back 4 decimal places(4 zeros)
= .0068

Which may or may not be close enough to the actual answer :
0.0068700389655581563026901232399755
