We look at the division of 97296874 by 831 
The aim is to understand the frequency of 831 in 97296874.

Advancing to step 1:
If we divide 9 by 831, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 831

Moving on to step 2:
If we divide 97 by 831, we get 0 and a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Bring next digit (2) of the dividend behind the 97 and repeat the process: 972 / 831

Moving on to step 3:
972 divided by 831 is 1 with a remainder of 141.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 141 after subtracting 831 from 972.
Bring next digit (9) of the dividend behind the 141 and repeat the process: 1419 / 831

Advancing to step 4:
The number 831 fits into 1419 1 times, leaving a remainder of 588.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 588 after subtracting 831 from 1419.
Include the next digit (6) from the dividend after 588, then repeat: 5886 / 831

Going ahead to step 5:
If we divide 5886 by 831, we get 7 and a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtract 5817 from 5886 to get 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 831

Moving on to step 6:
698 divided by 831 is 0 with a remainder of 698.
Record the quotient 0 as the next digit in the result. 
Result so far: 1170.0
The remainder is 698 after subtracting 0 from 698.
Grab the next digit (7) from the dividend, add it to 698, then carry on: 6987 / 831

On to step 7:
6987 divided by 831 is 8 with a remainder of 339.
The next digit of our result is 8. 
Result so far: 11708.0
If we subtract 6648 from 6987, we get 339.
Append the next digit (4) from the dividend to 339 and continue with: 3394 / 831

Step 8:
If we divide 3394 by 831, we get 4 and a remainder of 70.
The next digit of our result is 4. 
Result so far: 117084.0
If we subtract 3324 from 3394, we get 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 9:
831 goes into 700 0 times with a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 117084.0
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 10:
The number 831 fits into 7000 8 times, leaving a remainder of 352.
The number 8 becomes the next digit in our result. 
Result so far: 117084.08
Subtract 6648 from 7000 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 11:
831 can be fit into 3520 4 times, resulting in a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 117084.084
If we subtract 3324 from 3520, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 12:
831 goes into 1960 2 times with a remainder of 298.
Use 2 as the next digit of our solution. 
Result so far: 117084.0842
The remainder is 298 after subtracting 1662 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 13:
831 goes into 2980 3 times with a remainder of 487.
Put 3 as the next digit of the answer. 
Result so far: 117084.08423
If we take 2493 away from 2980, we end up with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Let's proceed to step 14:
831 can be fit into 4870 5 times, resulting in a remainder of 715.
Put 5 as the next digit of the answer. 
Result so far: 117084.084235
The remainder is 715 after subtracting 4155 from 4870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 15:
The number 831 fits into 7150 8 times, leaving a remainder of 502.
The next digit of our result is 8. 
Result so far: 117084.0842358
If we take 6648 away from 7150, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 16:
If we divide 5020 by 831, we get 6 and a remainder of 34.
The next digit of our result is 6. 
Result so far: 117084.08423586
If we take 4986 away from 5020, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 117084.08423586 with a balance of 3.4e-08.
