How many numbers end in the four digits 1995 and become an integer number of times smaller when these digits are erased?

I do not understand the question through but I think this is asking for all numbers of the form: 19951995 -> 1995

But since there is no restriction on the length so could we have a finite solution for this problem? If yes, how?

Thank you,

    Note that $\frac{199519951995}{19951995}$ is not an integer.2012-01-17
