We're dividing 83507759 by 831 
The aim is to understand the frequency of 831 in 83507759.

Step 1:
831 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 831

Moving on to step 2:
83 divided by 831 is 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 831

Advancing to step 3:
If we divide 835 by 831, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 831 from 835 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 831

Step 4:
831 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 831

Let's proceed to step 5:
407 divided by 831 is 0 with a remainder of 407.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 407, we get 407.
Bring next digit (7) of the dividend behind the 407 and repeat the process: 4077 / 831

Moving on to step 6:
The number 831 fits into 4077 4 times, leaving a remainder of 753.
The next digit of our result is 4. 
Result so far: 1004.0
Deduct 3324 from 4077 and we're left with 753.
Append the next digit (5) from the dividend to 753 and continue with: 7535 / 831

Step 7:
When dividing 7535 by 831, we get 9 with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 10049.0
If we take 7479 away from 7535, we end up with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 831

Advancing to step 8:
831 goes into 569 0 times with a remainder of 569.
Use 0 as the next digit of our solution. 
Result so far: 100490.0
If we take 0 away from 569, we end up with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Advancing to step 9:
When dividing 5690 by 831, we get 6 with a remainder of 704.
Use 6 as the next digit of our solution. 
Result so far: 100490.6
If we take 4986 away from 5690, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Moving on to step 10:
When dividing 7040 by 831, we get 8 with a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 100490.68
Subtracting 6648 from 7040 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 11:
831 can be fit into 3920 4 times, resulting in a remainder of 596.
Put 4 as the next digit of the answer. 
Result so far: 100490.684
The remainder is 596 after subtracting 3324 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 12:
When dividing 5960 by 831, we get 7 with a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 100490.6847
Deduct 5817 from 5960 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 13:
When dividing 1430 by 831, we get 1 with a remainder of 599.
Put 1 as the next digit of the answer. 
Result so far: 100490.68471
The remainder is 599 after subtracting 831 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Moving on to step 14:
The number 831 fits into 5990 7 times, leaving a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 100490.684717
Subtract 5817 from 5990 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 15:
The number 831 fits into 1730 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 100490.6847172
Deduct 1662 from 1730 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 16:
If we divide 680 by 831, we get 0 and a remainder of 680.
Put 0 as the next digit of the answer. 
Result so far: 100490.6847172
Deduct 0 from 680 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

In conclusion, the division gives 100490.6847172 with a balance of 6.8e-07.
