We divide 89820586 by 831
The aim is to understand the frequency of 831 in 89820586.

Going ahead to step 1:
The number 831 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 831

Advancing to step 2:
The number 831 fits into 89 0 times, leaving a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 831

On to step 3:
If we divide 898 by 831, we get 1 and a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 831 from 898 to get 67.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 831

Going ahead to step 4:
When dividing 672 by 831, we get 0 with a remainder of 672.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 672 after subtracting 0 from 672.
Grab the next digit (0) from the dividend, add it to 672, then carry on: 6720 / 831

Step 5:
The number 831 fits into 6720 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we subtract 6648 from 6720, we get 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 831

Going ahead to step 6:
If we divide 725 by 831, we get 0 and a remainder of 725.
Write down 0 as next digit of the result. 
Result so far: 1080.0
The remainder is 725 after subtracting 0 from 725.
Bring next digit (8) of the dividend behind the 725 and repeat the process: 7258 / 831

Going ahead to step 7:
7258 divided by 831 is 8 with a remainder of 610.
Use 8 as the next digit of our solution. 
Result so far: 10808.0
If we subtract 6648 from 7258, we get 610.
Fetch the next digit (6) from the dividend, attach it to 610 and continue: 6106 / 831

Moving on to step 8:
831 can be fit into 6106 7 times, resulting in a remainder of 289.
Use 7 as the next digit of our solution. 
Result so far: 108087.0
Subtracting 5817 from 6106 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 9:
If we divide 2890 by 831, we get 3 and a remainder of 397.
Record the quotient 3 as the next digit in the result. 
Result so far: 108087.3
If we subtract 2493 from 2890, we get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 10:
If we divide 3970 by 831, we get 4 and a remainder of 646.
The number 4 becomes the next digit in our result. 
Result so far: 108087.34
The remainder is 646 after subtracting 3324 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 11:
831 can be fit into 6460 7 times, resulting in a remainder of 643.
The next digit of our result is 7. 
Result so far: 108087.347
If we subtract 5817 from 6460, we get 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Advancing to step 12:
831 goes into 6430 7 times with a remainder of 613.
Use 7 as the next digit of our solution. 
Result so far: 108087.3477
The remainder is 613 after subtracting 5817 from 6430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

After the division, we end up with 108087.3477 and a remainder of 0.00613.
