57898751 ÷ 831 
The aim is to understand the frequency of 831 in 57898751.

Moving on to step 1:
5 divided by 831 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 831

Moving on to step 2:
The number 831 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 831

Going ahead to step 3:
831 can be fit into 578 0 times, resulting in a remainder of 578.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 578 and we're left with 578.
Append the next digit (9) from the dividend to 578 and continue with: 5789 / 831

Moving on to step 4:
If we divide 5789 by 831, we get 6 and a remainder of 803.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 4986 from 5789 leaves us with 803.
Append the next digit (8) from the dividend to 803 and continue with: 8038 / 831

On to step 5:
8038 divided by 831 is 9 with a remainder of 559.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we take 7479 away from 8038, we end up with 559.
Include the next digit (7) from the dividend after 559, then repeat: 5597 / 831

Let's proceed to step 6:
The number 831 fits into 5597 6 times, leaving a remainder of 611.
The number 6 becomes the next digit in our result. 
Result so far: 696.0
Subtract 4986 from 5597 to get 611.
Include the next digit (5) from the dividend after 611, then repeat: 6115 / 831

Moving on to step 7:
831 goes into 6115 7 times with a remainder of 298.
The next digit of our result is 7. 
Result so far: 6967.0
Subtracting 5817 from 6115 leaves us with 298.
Fetch the next digit (1) from the dividend, attach it to 298 and continue: 2981 / 831

On to step 8:
If we divide 2981 by 831, we get 3 and a remainder of 488.
The next digit of our result is 3. 
Result so far: 69673.0
The remainder is 488 after subtracting 2493 from 2981.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 9:
4880 divided by 831 is 5 with a remainder of 725.
Use 5 as the next digit of our solution. 
Result so far: 69673.5
Deduct 4155 from 4880 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Let's proceed to step 10:
If we divide 7250 by 831, we get 8 and a remainder of 602.
The next digit of our result is 8. 
Result so far: 69673.58
Subtract 6648 from 7250 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 11:
831 can be fit into 6020 7 times, resulting in a remainder of 203.
Put 7 as the next digit of the answer. 
Result so far: 69673.587
If we take 5817 away from 6020, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 12:
831 goes into 2030 2 times with a remainder of 368.
The number 2 becomes the next digit in our result. 
Result so far: 69673.5872
Subtracting 1662 from 2030 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 13:
831 goes into 3680 4 times with a remainder of 356.
Write down 4 as next digit of the result. 
Result so far: 69673.58724
Subtract 3324 from 3680 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 14:
3560 divided by 831 is 4 with a remainder of 236.
Use 4 as the next digit of our solution. 
Result so far: 69673.587244
Deduct 3324 from 3560 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final result is 69673.587244 with a remainder of 2.36e-05.
