In normal decimal notation, each digit is multiplied by 10 raised to the value of its position, starting from zero on the right.
If each of you would call out a single digit between zero and nine, that will be the four-digit number that I'll square.
One digit at a time, I shall try and determine the digit you've left out.
Does it have a digit?
The first digit indicates the quantity of zeroes, the second digit indicates the number of ones, the third digit the number of twos, and so on until the end.

So now we know that our number must contain at least three zeroes – which also means that the leading digit must be 3 or greater.
Now, while this first digit counts the number of zeroes, every digit after it counts how many times a particular non-zero digit occurs.
Well, we now know something important: the total quantity of non-zero digits that occur after the first digit is equal to the sum of these digits, minus one.
So now we have the leading digit of 3 or greater counting the zeroes, a 2 counting the 1s, and two 1s – one to count the 2s and another to count the leading digit.
