We look at the division of 57488018 by 831 
The aim is to understand the frequency of 831 in 57488018.

Step 1:
5 divided by 831 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 831

Step 2:
831 can be fit into 57 0 times, resulting in a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 831

Moving on to step 3:
574 divided by 831 is 0 with a remainder of 574.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 574 and we're left with 574.
Append the next digit (8) from the dividend to 574 and continue with: 5748 / 831

Advancing to step 4:
When dividing 5748 by 831, we get 6 with a remainder of 762.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 4986 from 5748 and we're left with 762.
Grab the next digit (8) from the dividend, add it to 762, then carry on: 7628 / 831

Advancing to step 5:
7628 divided by 831 is 9 with a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtracting 7479 from 7628 leaves us with 149.
Grab the next digit (0) from the dividend, add it to 149, then carry on: 1490 / 831

Going ahead to step 6:
If we divide 1490 by 831, we get 1 and a remainder of 659.
The next digit of our result is 1. 
Result so far: 691.0
Deduct 831 from 1490 and we're left with 659.
Grab the next digit (1) from the dividend, add it to 659, then carry on: 6591 / 831

Let's proceed to step 7:
831 goes into 6591 7 times with a remainder of 774.
The next digit of our result is 7. 
Result so far: 6917.0
If we take 5817 away from 6591, we end up with 774.
Take the next digit (8) from the dividend and append it to 774, then repeat: 7748 / 831

On to step 8:
831 goes into 7748 9 times with a remainder of 269.
Use 9 as the next digit of our solution. 
Result so far: 69179.0
If we take 7479 away from 7748, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 9:
831 can be fit into 2690 3 times, resulting in a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 69179.3
Subtracting 2493 from 2690 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 10:
831 can be fit into 1970 2 times, resulting in a remainder of 308.
Write down 2 as next digit of the result. 
Result so far: 69179.32
Deduct 1662 from 1970 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 11:
When dividing 3080 by 831, we get 3 with a remainder of 587.
The next digit of our result is 3. 
Result so far: 69179.323
Deduct 2493 from 3080 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

On to step 12:
When dividing 5870 by 831, we get 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 69179.3237
Deduct 5817 from 5870 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 13:
530 divided by 831 is 0 with a remainder of 530.
Use 0 as the next digit of our solution. 
Result so far: 69179.3237
Subtracting 0 from 530 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 14:
831 can be fit into 5300 6 times, resulting in a remainder of 314.
The number 6 becomes the next digit in our result. 
Result so far: 69179.323706
If we subtract 4986 from 5300, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 15:
If we divide 3140 by 831, we get 3 and a remainder of 647.
The number 3 becomes the next digit in our result. 
Result so far: 69179.3237063
If we subtract 2493 from 3140, we get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Step 16:
When dividing 6470 by 831, we get 7 with a remainder of 653.
Put 7 as the next digit of the answer. 
Result so far: 69179.32370637
If we subtract 5817 from 6470, we get 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

The final result is 69179.32370637 with a remainder of 6.53e-07.
