We look at the division of 28739274 by 83 
The aim is to understand the frequency of 83 in 28739274.

Advancing to step 1:
When dividing 2 by 83, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 83

Let's proceed to step 2:
The number 83 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 83

Advancing to step 3:
287 divided by 83 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 249 from 287 to get 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 83

Moving on to step 4:
83 can be fit into 383 4 times, resulting in a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 332 from 383, we get 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 83

Step 5:
When dividing 519 by 83, we get 6 with a remainder of 21.
The next digit of our result is 6. 
Result so far: 346.0
The remainder is 21 after subtracting 498 from 519.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 83

Step 6:
If we divide 212 by 83, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 3462.0
If we subtract 166 from 212, we get 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 83

Advancing to step 7:
The number 83 fits into 467 5 times, leaving a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 34625.0
If we take 415 away from 467, we end up with 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 83

Moving on to step 8:
The number 83 fits into 524 6 times, leaving a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 346256.0
Subtracting 498 from 524 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
If we divide 260 by 83, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 346256.3
The remainder is 11 after subtracting 249 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
83 goes into 110 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 346256.31
The remainder is 27 after subtracting 83 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
If we divide 270 by 83, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 346256.313
Deduct 249 from 270 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
The number 83 fits into 210 2 times, leaving a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 346256.3132
Subtract 166 from 210 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
83 can be fit into 440 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 346256.31325
If we subtract 415 from 440, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
83 goes into 250 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 346256.313253
Subtracting 249 from 250 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 15:
10 divided by 83 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 346256.313253
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
83 can be fit into 100 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 346256.31325301
If we subtract 83 from 100, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 346256.31325301 and a remainder of 1.7e-08.
