We look at the division of 12615 by 83 
The aim is to understand the frequency of 83 in 12615.

Going ahead to step 1:
If we divide 1 by 83, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 83

Step 2:
12 divided by 83 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 83

Moving on to step 3:
When dividing 126 by 83, we get 1 with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 83 from 126, we get 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 83

On to step 4:
83 goes into 431 5 times with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 415 from 431, we get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 83

Step 5:
When dividing 165 by 83, we get 1 with a remainder of 82.
The next digit of our result is 1. 
Result so far: 151.0
If we subtract 83 from 165, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 6:
83 goes into 820 9 times with a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 151.9
If we take 747 away from 820, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 7:
83 goes into 730 8 times with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 151.98
If we subtract 664 from 730, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
660 divided by 83 is 7 with a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 151.987
Deduct 581 from 660 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
790 divided by 83 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 151.9879
The remainder is 43 after subtracting 747 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 10:
The number 83 fits into 430 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 151.98795
Subtracting 415 from 430 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
When dividing 150 by 83, we get 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 151.987951
Deduct 83 from 150 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 12:
The number 83 fits into 670 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 151.9879518
The remainder is 6 after subtracting 664 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
When dividing 60 by 83, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 151.9879518
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 151.9879518 and a remainder of 6e-08.
