A number N consisting of a string of sevens
i.e. N=77777...7777, is divisible by 199.
Find the last 4 digits of the quotient.
No programming, please.

Hi,

I made public the "lucky seven" solution and in the final lines interchanged x and y and put capital C instead of c

SO:.......

"......Therefore d=3 and c=2

x=2*d=6

y=2*C=4

and the quotient's last figures are 6823."

**should be**:

,,,," Therefore d=3 and c=2

y=2*d=6

x=2*c=4

and the quotient's last figures are 6823."

All the rest is correct.

**6823 is the answer.**
