We're dividing 80732166 by 831 
The aim is to understand the frequency of 831 in 80732166.

Step 1:
The number 831 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 831

Moving on to step 2:
If we divide 80 by 831, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 831

On to step 3:
831 goes into 807 0 times with a remainder of 807.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 807, we end up with 807.
Bring next digit (3) of the dividend behind the 807 and repeat the process: 8073 / 831

Moving on to step 4:
8073 divided by 831 is 9 with a remainder of 594.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7479 from 8073 leaves us with 594.
Append the next digit (2) from the dividend to 594 and continue with: 5942 / 831

Let's proceed to step 5:
831 goes into 5942 7 times with a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we subtract 5817 from 5942, we get 125.
Append the next digit (1) from the dividend to 125 and continue with: 1251 / 831

On to step 6:
1251 divided by 831 is 1 with a remainder of 420.
Use 1 as the next digit of our solution. 
Result so far: 971.0
Subtracting 831 from 1251 leaves us with 420.
Include the next digit (6) from the dividend after 420, then repeat: 4206 / 831

Going ahead to step 7:
When dividing 4206 by 831, we get 5 with a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 9715.0
Subtracting 4155 from 4206 leaves us with 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 831

Advancing to step 8:
If we divide 516 by 831, we get 0 and a remainder of 516.
The next digit of our result is 0. 
Result so far: 97150.0
Subtract 0 from 516 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 9:
If we divide 5160 by 831, we get 6 and a remainder of 174.
Use 6 as the next digit of our solution. 
Result so far: 97150.6
Subtracting 4986 from 5160 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 10:
831 goes into 1740 2 times with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 97150.62
Subtract 1662 from 1740 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 11:
780 divided by 831 is 0 with a remainder of 780.
Put 0 as the next digit of the answer. 
Result so far: 97150.62
Subtract 0 from 780 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 12:
If we divide 7800 by 831, we get 9 and a remainder of 321.
The next digit of our result is 9. 
Result so far: 97150.6209
If we subtract 7479 from 7800, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 13:
If we divide 3210 by 831, we get 3 and a remainder of 717.
The next digit of our result is 3. 
Result so far: 97150.62093
Deduct 2493 from 3210 and we're left with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Advancing to step 14:
The number 831 fits into 7170 8 times, leaving a remainder of 522.
Put 8 as the next digit of the answer. 
Result so far: 97150.620938
The remainder is 522 after subtracting 6648 from 7170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 15:
831 goes into 5220 6 times with a remainder of 234.
The number 6 becomes the next digit in our result. 
Result so far: 97150.6209386
Subtracting 4986 from 5220 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 16:
The number 831 fits into 2340 2 times, leaving a remainder of 678.
The number 2 becomes the next digit in our result. 
Result so far: 97150.62093862
If we take 1662 away from 2340, we end up with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

The quotient of the division is 97150.62093862, and the remainder is 6.78e-07.
