We divide 81995914 by 831
The aim is to understand the frequency of 831 in 81995914.

Advancing to step 1:
The number 831 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 831

Advancing to step 2:
When dividing 81 by 831, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 831

On to step 3:
831 can be fit into 819 0 times, resulting in a remainder of 819.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 819 after subtracting 0 from 819.
Take the next digit (9) from the dividend and append it to 819, then repeat: 8199 / 831

On to step 4:
831 goes into 8199 9 times with a remainder of 720.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7479 from 8199, we get 720.
Include the next digit (5) from the dividend after 720, then repeat: 7205 / 831

Let's proceed to step 5:
831 goes into 7205 8 times with a remainder of 557.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
The remainder is 557 after subtracting 6648 from 7205.
Include the next digit (9) from the dividend after 557, then repeat: 5579 / 831

Step 6:
831 goes into 5579 6 times with a remainder of 593.
The next digit of our result is 6. 
Result so far: 986.0
Subtract 4986 from 5579 to get 593.
Take the next digit (1) from the dividend and append it to 593, then repeat: 5931 / 831

Advancing to step 7:
831 can be fit into 5931 7 times, resulting in a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 9867.0
The remainder is 114 after subtracting 5817 from 5931.
Take the next digit (4) from the dividend and append it to 114, then repeat: 1144 / 831

Step 8:
When dividing 1144 by 831, we get 1 with a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 98671.0
The remainder is 313 after subtracting 831 from 1144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 9:
3130 divided by 831 is 3 with a remainder of 637.
Write down 3 as next digit of the result. 
Result so far: 98671.3
If we take 2493 away from 3130, we end up with 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

On to step 10:
6370 divided by 831 is 7 with a remainder of 553.
The next digit of our result is 7. 
Result so far: 98671.37
Subtracting 5817 from 6370 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Let's proceed to step 11:
If we divide 5530 by 831, we get 6 and a remainder of 544.
The next digit of our result is 6. 
Result so far: 98671.376
If we subtract 4986 from 5530, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 12:
831 can be fit into 5440 6 times, resulting in a remainder of 454.
Put 6 as the next digit of the answer. 
Result so far: 98671.3766
If we subtract 4986 from 5440, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Our division results in 98671.3766 with a remaining 0.00454.
