We're dividing 79852578 by 831 
The aim is to understand the frequency of 831 in 79852578.

Let's proceed to step 1:
When dividing 7 by 831, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 831

Let's proceed to step 2:
If we divide 79 by 831, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 831

Advancing to step 3:
The number 831 fits into 798 0 times, leaving a remainder of 798.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 798 and we're left with 798.
Append the next digit (5) from the dividend to 798 and continue with: 7985 / 831

Step 4:
831 goes into 7985 9 times with a remainder of 506.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 7479 from 7985 and we're left with 506.
Append the next digit (2) from the dividend to 506 and continue with: 5062 / 831

Step 5:
831 can be fit into 5062 6 times, resulting in a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we take 4986 away from 5062, we end up with 76.
Append the next digit (5) from the dividend to 76 and continue with: 765 / 831

Let's proceed to step 6:
If we divide 765 by 831, we get 0 and a remainder of 765.
Use 0 as the next digit of our solution. 
Result so far: 960.0
Subtract 0 from 765 to get 765.
Bring next digit (7) of the dividend behind the 765 and repeat the process: 7657 / 831

Step 7:
The number 831 fits into 7657 9 times, leaving a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 9609.0
Deduct 7479 from 7657 and we're left with 178.
Take the next digit (8) from the dividend and append it to 178, then repeat: 1788 / 831

Advancing to step 8:
If we divide 1788 by 831, we get 2 and a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 96092.0
Subtract 1662 from 1788 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 9:
1260 divided by 831 is 1 with a remainder of 429.
Record the quotient 1 as the next digit in the result. 
Result so far: 96092.1
If we subtract 831 from 1260, we get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 10:
831 goes into 4290 5 times with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 96092.15
Subtract 4155 from 4290 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 11:
1350 divided by 831 is 1 with a remainder of 519.
The next digit of our result is 1. 
Result so far: 96092.151
Deduct 831 from 1350 and we're left with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Going ahead to step 12:
When dividing 5190 by 831, we get 6 with a remainder of 204.
The next digit of our result is 6. 
Result so far: 96092.1516
Subtracting 4986 from 5190 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 13:
2040 divided by 831 is 2 with a remainder of 378.
Put 2 as the next digit of the answer. 
Result so far: 96092.15162
Deduct 1662 from 2040 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 14:
831 can be fit into 3780 4 times, resulting in a remainder of 456.
Use 4 as the next digit of our solution. 
Result so far: 96092.151624
The remainder is 456 after subtracting 3324 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 15:
When dividing 4560 by 831, we get 5 with a remainder of 405.
Write down 5 as next digit of the result. 
Result so far: 96092.1516245
Deduct 4155 from 4560 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 16:
831 can be fit into 4050 4 times, resulting in a remainder of 726.
The next digit of our result is 4. 
Result so far: 96092.15162454
The remainder is 726 after subtracting 3324 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

After the division, we end up with 96092.15162454 and a remainder of 7.26e-07.
