We look at the division of 674574 by 83 
The aim is to understand the frequency of 83 in 674574.

Step 1:
83 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 83

Advancing to step 2:
If we divide 67 by 83, we get 0 and a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 83

Let's proceed to step 3:
If we divide 674 by 83, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 664 from 674, we get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 83

On to step 4:
The number 83 fits into 105 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 22 after subtracting 83 from 105.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 83

Moving on to step 5:
227 divided by 83 is 2 with a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 812.0
Subtract 166 from 227 to get 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 83

Step 6:
If we divide 614 by 83, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 8127.0
Deduct 581 from 614 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
When dividing 330 by 83, we get 3 with a remainder of 81.
The next digit of our result is 3. 
Result so far: 8127.3
If we subtract 249 from 330, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 8:
83 can be fit into 810 9 times, resulting in a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 8127.39
If we take 747 away from 810, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
83 goes into 630 7 times with a remainder of 49.
The next digit of our result is 7. 
Result so far: 8127.397
If we subtract 581 from 630, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
490 divided by 83 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 8127.3975
Subtract 415 from 490 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
83 goes into 750 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 8127.39759
Subtracting 747 from 750 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
The number 83 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8127.39759
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
300 divided by 83 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 8127.3975903
Subtract 249 from 300 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 14:
If we divide 510 by 83, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 8127.39759036
If we subtract 498 from 510, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8127.39759036 with a remaining 1.2e-08.
