This problem’s question: Each letter stands for a decimal digit. Each identical letter represents the same decimal digit each time the letter occurs. The period is a decimal point. To the left of the equal sign is a fraction. Write the answer as EVEDID. What is the answer?
Clarification: I lost the four-dot ellipsis in the title meant to indicate that decimal representation was a repeating decimal fraction. It is a coincidence that the ellipsis is four dots long and the repeat interval of the repeating decimal fraction is also four digits long.
DID EVE = . TALK TALK ⋅ ⋅ ⋅ or DID EVE = . T ˙ AL K ˙ TALK ⋅ ⋅ ⋅
Second clarification (due to Chris Lewis): DID EVE is a reduced fraction, i. e., the numerator and denominator are co-prime.

. We're sorry about the hassle.
the decimal representation of the fraction is not exactly 0 . 7 9 8 6 7 9 8 6
You are correct. I added a clarification to explain that fact. Please, delete your report.

You have posted a faulty question and I just shared my opinion in the comment part (it's not a report). Why should I delete my comment?

Sorry. I misunderstood. By all means, leave the comment. It is only reports that cause problems for the author of a problem by nagging the author until the report is deleted. Comment cause no such problem.
I do believe that my clarification handles the problem.
You may want to add that the fraction is in lowest terms, otherwise 6 0 6 2 1 2 = 0 . 3 4 9 8 is another valid solution (I believe it's the only other one).
Ouch, that hurts. I only checked divisors of 9999, which implicitly requires reduced fractions.

The fraction is a proper fraction as there is nothing to the left of the decimal point. DID is a factor of 9999. The divisors of 9999 in the proper form as 101, 303 and 909. 101 does not work as that would require E to be equal to T. 909 does not work as that would require E to be equal to K. Therefore, DID is 303. E is 1 or 2, otherwise this would not be a proper fraction. Therefore, EVE is 121, 141, 151, 161, 171, 181 or 191, 212, 141, 151, 161, 171, 181 or 191. Only the value of 242 for EVE does not result in TALK needing an already used digit. Therefore the answer is 242303.
