We look at the division of 848738 by 83 
The aim is to understand the frequency of 83 in 848738.

Advancing to step 1:
If we divide 8 by 83, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 83

Step 2:
84 divided by 83 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 83 from 84.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 83

Going ahead to step 3:
If we divide 18 by 83, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 83

Going ahead to step 4:
187 divided by 83 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we subtract 166 from 187, we get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 83

Let's proceed to step 5:
83 goes into 213 2 times with a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 1022.0
Deduct 166 from 213 and we're left with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 83

Step 6:
If we divide 478 by 83, we get 5 and a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 10225.0
Deduct 415 from 478 and we're left 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.

Advancing to step 7:
83 can be fit into 630 7 times, resulting in a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 10225.7
Subtract 581 from 630 to 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.

Let's proceed to step 8:
The number 83 fits into 490 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 10225.75
Subtracting 415 from 490 leaves us with 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 9:
83 goes into 750 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 10225.759
If we take 747 away from 750, we end up 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 10:
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: 10225.759
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.

On to step 11:
300 divided by 83 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 10225.75903
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.

Moving on to step 12:
510 divided by 83 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10225.759036
Deduct 498 from 510 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
83 can be fit into 120 1 times, resulting in a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 10225.7590361
Subtracting 83 from 120 leaves us with 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 14:
83 goes into 370 4 times with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 10225.75903614
If we take 332 away from 370, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 10225.75903614 with a remainder of 3.8e-08.
