68918311 divided by 811 
The aim is to understand the frequency of 811 in 68918311.

Let's proceed to step 1:
The number 811 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 811

Advancing to step 2:
When dividing 68 by 811, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 811

Let's proceed to step 3:
When dividing 689 by 811, we get 0 with a remainder of 689.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 689, we get 689.
Fetch the next digit (1) from the dividend, attach it to 689 and continue: 6891 / 811

Advancing to step 4:
6891 divided by 811 is 8 with a remainder of 403.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6488 from 6891 to get 403.
Include the next digit (8) from the dividend after 403, then repeat: 4038 / 811

On to step 5:
The number 811 fits into 4038 4 times, leaving a remainder of 794.
The next digit of our result is 4. 
Result so far: 84.0
If we take 3244 away from 4038, we end up with 794.
Bring next digit (3) of the dividend behind the 794 and repeat the process: 7943 / 811

Moving on to step 6:
When dividing 7943 by 811, we get 9 with a remainder of 644.
The next digit of our result is 9. 
Result so far: 849.0
The remainder is 644 after subtracting 7299 from 7943.
Take the next digit (1) from the dividend and append it to 644, then repeat: 6441 / 811

Step 7:
811 can be fit into 6441 7 times, resulting in a remainder of 764.
Use 7 as the next digit of our solution. 
Result so far: 8497.0
If we subtract 5677 from 6441, we get 764.
Bring next digit (1) of the dividend behind the 764 and repeat the process: 7641 / 811

Let's proceed to step 8:
7641 divided by 811 is 9 with a remainder of 342.
The next digit of our result is 9. 
Result so far: 84979.0
If we take 7299 away from 7641, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 9:
When dividing 3420 by 811, we get 4 with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 84979.4
Subtract 3244 from 3420 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 10:
811 goes into 1760 2 times with a remainder of 138.
Use 2 as the next digit of our solution. 
Result so far: 84979.42
If we take 1622 away from 1760, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 11:
811 can be fit into 1380 1 times, resulting in a remainder of 569.
The next digit of our result is 1. 
Result so far: 84979.421
Deduct 811 from 1380 and we're left 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.

Going ahead to step 12:
If we divide 5690 by 811, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 84979.4217
If we take 5677 away from 5690, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
If we divide 130 by 811, we get 0 and a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 84979.4217
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
811 goes into 1300 1 times with a remainder of 489.
The next digit of our result is 1. 
Result so far: 84979.421701
Deduct 811 from 1300 and we're left with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Going ahead to step 15:
The number 811 fits into 4890 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 84979.4217016
The remainder is 24 after subtracting 4866 from 4890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 16:
811 can be fit into 240 0 times, resulting in a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 84979.4217016
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 84979.4217016 with a balance of 2.4e-07.
