Solution to:
Elegant Equation
Make a long division:
4/4.....\......
Calculate the first digit of the result:
4/4.....\1.....
4
--
0
Now we also know that the next digit of the dividend is a 1:
4/41....\1.....
4
--
0
Then we can calculate the next digit of the result:
4/41....\10....
4
--
01
0
--
1
So the next digit of the dividend is also a 0:
4/410...\10....
4
--
01
0
--
1
This process of calculating the next digit of the result and adding it to
the dividend must be repeated until the remainder is 0 and the last digit
of the result is a 4:
4/410256\102564
