15213 divided by 83 
The aim is to understand the frequency of 83 in 15213.

Step 1:
The number 83 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 83

Moving on to step 2:
15 divided by 83 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 83

Moving on to step 3:
83 can be fit into 152 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 1.0

The next digit of our result is 9. 
Result so far: 183.289
If we take 747 away from 760, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 83, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 183.2891
Subtracting 83 from 130 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
When dividing 470 by 83, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 183.28915
Deduct 415 from 470 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 11:
550 divided by 83 is 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 183.289156
The remainder is 52 after subtracting 498 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
520 divided by 83 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 183.2891566
Subtracting 498 from 520 leaves us with 22.
