A047841: Autobiographical numbers Definition

Here is the process to describe a number:


For each number from 0 to 9 that is present in the number:
Write down the frequency of that digit and then the digit.


For example, for the number 10213223:


There is 1 occurrence of 0,
2 occurrences of 1,
3 occurrences of 2,
2 occurrences of 3.


Therefore, the number that describes 10213223 is 10213223 (10 from the first property, 21 from the second, etc.).

Note that the number of occurrences of a digit may be greater than 9.

Task

You are to print/output all numbers that describe themselves.

Specs


Standard loopholes apply, except that you are allowed to hardcode the output or store information related to the output in your program.
The numbers in the output can be in any order.
The numbers in the output are allowed to have duplicates.
You may use any separator, if you choose to print instead of output.
You are allowed to prefix and/or postfix output if you choose to print instead of output.
The separator and the prefix and the postfix may not contain any digits (U+0030 to U+0039).
The solution must compute in one day.

(line breaks and tabs for clarity)

It's a simple counter which uses the fact that each number has a limited occurrence. For instance is 0 no more than one time in any number, 1 no more than 11 times, 2 no more than 3 times ... and so on.

This way there are only 124415 numbers to check.

It then creates all numbers and checks their validity.
