We look at the division of 999374 by 83 
The aim is to understand the frequency of 83 in 999374.

On to step 1:
9 divided by 83 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 83

On to step 2:
83 can be fit into 99 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 83 from 99 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 83

Going ahead to step 3:
When dividing 169 by 83, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 166 from 169 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 83

Moving on to step 4:
83 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 120.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 83

Step 5:
83 goes into 337 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 1204.0
The remainder is 5 after subtracting 332 from 337.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 83

Let's proceed to step 6:
If we divide 54 by 83, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 12040.0
If we subtract 0 from 54, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
83 goes into 540 6 times with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 12040.6
Subtracting 498 from 540 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
83 can be fit into 420 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 12040.65
If we subtract 415 from 420, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 83 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 12040.65
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
83 can be fit into 500 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 12040.6506
If we subtract 498 from 500, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
When dividing 20 by 83, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12040.6506
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
200 divided by 83 is 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 12040.650602
Deduct 166 from 200 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
83 goes into 340 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 12040.6506024
Subtracting 332 from 340 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
The number 83 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 12040.6506024
If we take 0 away from 80, we end up 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.

The final result is 12040.6506024 with a remainder of 8e-08.
