We look at the division of 108158 by 83 
The aim is to understand the frequency of 83 in 108158.

On to step 1:
83 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 83

Step 2:
10 divided by 83 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 83

On to step 3:
83 can be fit into 108 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 83 from 108 to get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 83

Let's proceed to step 4:
If we divide 251 by 83, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 249 from 251 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 83

Step 5:
When dividing 25 by 83, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtract 0 from 25 to get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 83

On to step 6:
The number 83 fits into 258 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 1303.0
If we subtract 249 from 258, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
83 goes into 90 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1303.1
If we subtract 83 from 90, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
83 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1303.1
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
If we divide 700 by 83, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1303.108
If we subtract 664 from 700, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
When dividing 360 by 83, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 1303.1084
Deduct 332 from 360 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
When dividing 280 by 83, we get 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 1303.10843
Subtract 249 from 280 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
When dividing 310 by 83, we get 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 1303.108433
If we subtract 249 from 310, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 1303.108433 with a remainder of 6.1e-06.
