We're dividing 81168324 by 311 
The aim is to understand the frequency of 311 in 81168324.

Advancing to step 1:
The number 311 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 311

Let's proceed to step 2:
311 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 311

Advancing to step 3:
The number 311 fits into 811 2 times, leaving a remainder of 189.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 622 from 811 leaves us with 189.
Take the next digit (6) from the dividend and append it to 189, then repeat: 1896 / 311

Moving on to step 4:
The number 311 fits into 1896 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 1866 from 1896, we get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 311

Moving on to step 5:
When dividing 308 by 311, we get 0 with a remainder of 308.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
The remainder is 308 after subtracting 0 from 308.
Append the next digit (3) from the dividend to 308 and continue with: 3083 / 311

Moving on to step 6:
If we divide 3083 by 311, we get 9 and a remainder of 284.
Put 9 as the next digit of the answer. 
Result so far: 2609.0
If we subtract 2799 from 3083, we get 284.
Append the next digit (2) from the dividend to 284 and continue with: 2842 / 311

On to step 7:
311 can be fit into 2842 9 times, resulting in a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 26099.0
Subtract 2799 from 2842 to get 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 311

Step 8:
When dividing 434 by 311, we get 1 with a remainder of 123.
The next digit of our result is 1. 
Result so far: 260991.0
The remainder is 123 after subtracting 311 from 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
If we divide 1230 by 311, we get 3 and a remainder of 297.
Put 3 as the next digit of the answer. 
Result so far: 260991.3
The remainder is 297 after subtracting 933 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Step 10:
The number 311 fits into 2970 9 times, leaving a remainder of 171.
The next digit of our result is 9. 
Result so far: 260991.39
Subtract 2799 from 2970 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 11:
1710 divided by 311 is 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 260991.395
Deduct 1555 from 1710 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 12:
311 goes into 1550 4 times with a remainder of 306.
Use 4 as the next digit of our solution. 
Result so far: 260991.3954
Deduct 1244 from 1550 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 13:
3060 divided by 311 is 9 with a remainder of 261.
The number 9 becomes the next digit in our result. 
Result so far: 260991.39549
Subtracting 2799 from 3060 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 14:
The number 311 fits into 2610 8 times, leaving a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 260991.395498
Subtracting 2488 from 2610 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 15:
1220 divided by 311 is 3 with a remainder of 287.
The number 3 becomes the next digit in our result. 
Result so far: 260991.3954983
If we subtract 933 from 1220, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 16:
When dividing 2870 by 311, we get 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 260991.39549839
Subtracting 2799 from 2870 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 260991.39549839, and the remainder is 7.1e-08.
