We look at the division of 235603 by 83 
The aim is to understand the frequency of 83 in 235603.

Let's proceed to step 1:
2 divided by 83 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 83

Moving on to step 2:
The number 83 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 83

Let's proceed to step 3:
If we divide 235 by 83, we get 2 and a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 166 from 235 leaves us with 69.
Fetch the next digit (6) from the dividend, attach it to 69 and continue: 696 / 83

Moving on to step 4:
If we divide 696 by 83, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 32 after subtracting 664 from 696.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 83

Going ahead to step 5:
When dividing 320 by 83, we get 3 with a remainder of 71.
The next digit of our result is 3. 
Result so far: 283.0
Subtract 249 from 320 to get 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 83

On to step 6:
713 divided by 83 is 8 with a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 2838.0
Subtracting 664 from 713 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
83 can be fit into 490 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 2838.5
If we subtract 415 from 490, we 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.

Moving on to step 8:
If we divide 750 by 83, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 2838.59
Deduct 747 from 750 and we're left 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.

Let's proceed to step 9:
When dividing 30 by 83, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 2838.59
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
83 goes into 300 3 times with a remainder of 51.
The next digit of our result is 3. 
Result so far: 2838.5903
If we take 249 away from 300, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
When dividing 510 by 83, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 2838.59036
Subtract 498 from 510 to 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.

Step 12:
If we divide 120 by 83, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 2838.590361
Subtract 83 from 120 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
If we divide 370 by 83, we get 4 and a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 2838.5903614
Subtract 332 from 370 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
83 can be fit into 380 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 2838.59036144
Subtract 332 from 380 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 2838.59036144 with a balance of 4.8e-08.
