We look at the division of 100331 by 83 
The aim is to understand the frequency of 83 in 100331.

Step 1:
1 divided by 83 is 0 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.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 83

On to step 2:
83 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 83

Going ahead to step 3:
When dividing 100 by 83, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 83 from 100 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 83

Step 4:
When dividing 173 by 83, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 166 from 173 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 83

Let's proceed to step 5:
When dividing 73 by 83, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 120.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 83

Step 6:
When dividing 731 by 83, we get 8 with a remainder of 67.
Record the quotient 8 as the next digit in the result. 
Result so far: 1208.0
Deduct 664 from 731 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
The number 83 fits into 670 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1208.8
If we subtract 664 from 670, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
When dividing 60 by 83, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1208.8
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
If we divide 600 by 83, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 1208.807
If we take 581 away from 600, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
190 divided by 83 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 1208.8072
The remainder is 24 after subtracting 166 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
240 divided by 83 is 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 1208.80722
If we take 166 away from 240, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 1208.80722 with a remaining 7.4e-05.
