Let's divide 62571372 by 831
The aim is to understand the frequency of 831 in 62571372.

On to step 1:
If we divide 6 by 831, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 831

Advancing to step 2:
When dividing 62 by 831, we get 0 with a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 831

Going ahead to step 3:
831 can be fit into 625 0 times, resulting in a remainder of 625.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 625 and we're left with 625.
Append the next digit (7) from the dividend to 625 and continue with: 6257 / 831

Moving on to step 4:
6257 divided by 831 is 7 with a remainder of 440.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 5817 from 6257 leaves us with 440.
Fetch the next digit (1) from the dividend, attach it to 440 and continue: 4401 / 831

Moving on to step 5:
When dividing 4401 by 831, we get 5 with a remainder of 246.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Deduct 4155 from 4401 and we're left with 246.
Take the next digit (3) from the dividend and append it to 246, then repeat: 2463 / 831

Step 6:
831 goes into 2463 2 times with a remainder of 801.
Write down 2 as next digit of the result. 
Result so far: 752.0
If we take 1662 away from 2463, we end up with 801.
Fetch the next digit (7) from the dividend, attach it to 801 and continue: 8017 / 831

On to step 7:
When dividing 8017 by 831, we get 9 with a remainder of 538.
Record the quotient 9 as the next digit in the result. 
Result so far: 7529.0
Subtract 7479 from 8017 to get 538.
Bring next digit (2) of the dividend behind the 538 and repeat the process: 5382 / 831

Moving on to step 8:
The number 831 fits into 5382 6 times, leaving a remainder of 396.
The number 6 becomes the next digit in our result. 
Result so far: 75296.0
Subtracting 4986 from 5382 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 9:
When dividing 3960 by 831, we get 4 with a remainder of 636.
The next digit of our result is 4. 
Result so far: 75296.4
Subtracting 3324 from 3960 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 10:
831 goes into 6360 7 times with a remainder of 543.
Record the quotient 7 as the next digit in the result. 
Result so far: 75296.47
The remainder is 543 after subtracting 5817 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Going ahead to step 11:
When dividing 5430 by 831, we get 6 with a remainder of 444.
Record the quotient 6 as the next digit in the result. 
Result so far: 75296.476
The remainder is 444 after subtracting 4986 from 5430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 12:
831 can be fit into 4440 5 times, resulting in a remainder of 285.
The next digit of our result is 5. 
Result so far: 75296.4765
If we take 4155 away from 4440, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 13:
831 can be fit into 2850 3 times, resulting in a remainder of 357.
The number 3 becomes the next digit in our result. 
Result so far: 75296.47653
Subtract 2493 from 2850 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Let's proceed to step 14:
The number 831 fits into 3570 4 times, leaving a remainder of 246.
Record the quotient 4 as the next digit in the result. 
Result so far: 75296.476534
If we subtract 3324 from 3570, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 15:
831 goes into 2460 2 times with a remainder of 798.
The next digit of our result is 2. 
Result so far: 75296.4765342
If we subtract 1662 from 2460, we get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Moving on to step 16:
The number 831 fits into 7980 9 times, leaving a remainder of 501.
The number 9 becomes the next digit in our result. 
Result so far: 75296.47653429
If we subtract 7479 from 7980, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

The final result is 75296.47653429 with a remainder of 5.01e-07.
