We look at the division of 80020 by 83 
The aim is to understand the frequency of 83 in 80020.

Let's proceed to step 1:
When dividing 8 by 83, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 83

Advancing to step 2:
When dividing 80 by 83, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 83

Advancing to step 3:
83 goes into 800 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 747 from 800 leaves us with 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 83

Going ahead to step 4:
83 can be fit into 532 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 498 away from 532, we end up with 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 83

Let's proceed to step 5:
When dividing 340 by 83, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 964.0
Subtract 332 from 340 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 6:
83 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 964.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 7:
If we divide 800 by 83, we get 9 and a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 964.09
If we subtract 747 from 800, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 8:
The number 83 fits into 530 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 964.096
If we subtract 498 from 530, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
83 can be fit into 320 3 times, resulting in a remainder of 71.
The next digit of our result is 3. 
Result so far: 964.0963
Deduct 249 from 320 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 10:
83 can be fit into 710 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 964.09638
Deduct 664 from 710 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
83 can be fit into 460 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 964.096385
Subtracting 415 from 460 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
83 can be fit into 450 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 964.0963855
If we take 415 away from 450, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 964.0963855 with a remainder of 3.5e-07.
