We're dividing 13647748 by 811 
The aim is to understand the frequency of 811 in 13647748.

Let's proceed to step 1:
When dividing 1 by 811, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 811

Advancing to step 2:
The number 811 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 811

Going ahead to step 3:
The number 811 fits into 136 0 times, leaving a remainder of 136.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 136 after subtracting 0 from 136.
Include the next digit (4) from the dividend after 136, then repeat: 1364 / 811

Step 4:
The number 811 fits into 1364 1 times, leaving a remainder of 553.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 811 from 1364 and we're left with 553.
Include the next digit (7) from the dividend after 553, then repeat: 5537 / 811

Moving on to step 5:
The number 811 fits into 5537 6 times, leaving a remainder of 671.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 671 after subtracting 4866 from 5537.
Bring next digit (7) of the dividend behind the 671 and repeat the process: 6717 / 811

On to step 6:
811 goes into 6717 8 times with a remainder of 229.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Subtract 6488 from 6717 to get 229.
Bring next digit (4) of the dividend behind the 229 and repeat the process: 2294 / 811

Advancing to step 7:
If we divide 2294 by 811, we get 2 and a remainder of 672.
Use 2 as the next digit of our solution. 
Result so far: 1682.0
If we subtract 1622 from 2294, we get 672.
Include the next digit (8) from the dividend after 672, then repeat: 6728 / 811

Going ahead to step 8:
811 can be fit into 6728 8 times, resulting in a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 16828.0
Subtracting 6488 from 6728 leaves us 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.

Advancing to step 9:
If we divide 2400 by 811, we get 2 and a remainder of 778.
Record the quotient 2 as the next digit in the result. 
Result so far: 16828.2
The remainder is 778 after subtracting 1622 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Let's proceed to step 10:
When dividing 7780 by 811, we get 9 with a remainder of 481.
Use 9 as the next digit of our solution. 
Result so far: 16828.29
Subtracting 7299 from 7780 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Advancing to step 11:
811 goes into 4810 5 times with a remainder of 755.
Record the quotient 5 as the next digit in the result. 
Result so far: 16828.295
The remainder is 755 after subtracting 4055 from 4810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Going ahead to step 12:
811 can be fit into 7550 9 times, resulting in a remainder of 251.
Record the quotient 9 as the next digit in the result. 
Result so far: 16828.2959
Subtract 7299 from 7550 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 13:
When dividing 2510 by 811, we get 3 with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 16828.29593
If we subtract 2433 from 2510, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 14:
The number 811 fits into 770 0 times, leaving a remainder of 770.
The next digit of our result is 0. 
Result so far: 16828.29593
Subtract 0 from 770 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

On to step 15:
7700 divided by 811 is 9 with a remainder of 401.
The next digit of our result is 9. 
Result so far: 16828.2959309
Subtract 7299 from 7700 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 16:
When dividing 4010 by 811, we get 4 with a remainder of 766.
Record the quotient 4 as the next digit in the result. 
Result so far: 16828.29593094
If we subtract 3244 from 4010, we get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

In conclusion, the division gives 16828.29593094 with a balance of 7.66e-07.
