Problem
Reconstruct this long division, where most of the digits are
represented with asterisks and a few sevens are given.
I warned you, this one is not for the faint-hearted, but it does have a
solution.
The following is a long division, where most of the numbers are
represented with asterisks. A few sevens are thrown in to make it
solvable, although I haven't seen anyone who could solve it, without
looking it up in the back of the book.
Here goes, I hope I don't make any typos.
