726863 ÷ 83 
The aim is to understand the frequency of 83 in 726863.

Going ahead to step 1:
The number 83 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 83

Moving on to step 2:
If we divide 72 by 83, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 83

Moving on to step 3:
83 can be fit into 726 8 times, resulting in a remainder of 62.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 664 from 726, we get 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 83

Let's proceed to step 4:
When dividing 628 by 83, we get 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 581 away from 628, we end up with 47.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 83

On to step 5:
The number 83 fits into 476 5 times, leaving a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 875.0
If we take 415 away from 476, we end up with 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 83

Let's proceed to step 6:
83 can be fit into 613 7 times, resulting in a remainder of 32.
The next digit of our result is 7. 
Result so far: 8757.0
Subtracting 581 from 613 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
When dividing 320 by 83, we get 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 8757.3
The remainder is 71 after subtracting 249 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 8:
If we divide 710 by 83, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 8757.38
Deduct 664 from 710 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
460 divided by 83 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 8757.385
If we take 415 away from 460, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
450 divided by 83 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8757.3855
Subtract 415 from 450 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 8757.3855 with a remainder of 0.00035.
