List all positive integers such that deleting their first digit is equal to dividing the number by 25.

You took the same approach as I.
One correction, as you left off 625 (if k is a non-negative integer -- as-is, if k = -1, 6250×10^k will account for the "missed" number).
The full number is 625×10^k OR 3125×10^k OR 9375×10^k, such that k is an element of the non-negative integers.
