We look at the division of 831138 by 83 
The aim is to understand the frequency of 83 in 831138.

On to step 1:
83 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 83

On to step 2:
83 divided by 83 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 83 from 83 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 83

Moving on to step 3:
If we divide 1 by 83, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 83

Advancing to step 4:
If we divide 11 by 83, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 100.0
If we subtract 0 from 11, we get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 83

Step 5:
83 can be fit into 113 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1001.0
If we subtract 83 from 113, we get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 83

Moving on to step 6:
If we divide 308 by 83, we get 3 and a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 10013.0
Subtracting 249 from 308 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
83 goes into 590 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 10013.7
The remainder is 9 after subtracting 581 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
90 divided by 83 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 10013.71
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.

Going ahead to step 9:
If we divide 70 by 83, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 10013.71
If we take 0 away from 70, we end up 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.

Let's proceed to step 10:
The number 83 fits into 700 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 10013.7108
Subtracting 664 from 700 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
360 divided by 83 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 10013.71084
Subtract 332 from 360 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
83 goes into 280 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 10013.710843
Deduct 249 from 280 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 13:
83 goes into 310 3 times with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 10013.7108433
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.

Our division results in 10013.7108433 with a remaining 6.1e-07.
