How do I use Javascript to figure out the quantity of 1000s, 100s, 10s, 1s in a number? [closed]

Here's an example of what I'm trying to do...

Let's say I have the number 73,284.

The number of thousands is 73 (73,284 divided by 1,000).

The number of hundreds is 2 (284 divided by 100).

The number of tens is 8 (84 divided by 10).

The number of singles is 4 (4 is left).

What I need is a Javascript function that would take the number 73,284 and create 4 numbers from it using the criteria above.

So if the number was 73,284, I'd pass that number into the function as a parameter and the function would return an array that looks like this, [73,2,8,4].

I tried to use the Math.round() function. It seemed to work for the thousands, but not necessarily for the hundreds, tens, and singles.
