A way to solve long division in 1/10th the time.
It only works "well" if you can round denominator up to easy number to solve without making the "factor" too high.
Here is another shortcut.... ANY number / 9
1234/9
= 1, (1+2), (1+2+3) R (1+2+3+4)
.... or 137 R 1
Shortcut for 5
1234/5 double each of the top numbers (except last digit which is remainder)
= 246 R 4
