11294851 ÷ 81 
The aim is to understand the frequency of 81 in 11294851.

Moving on to step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 81

Let's proceed to step 2:
81 goes into 11 0 times with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 81

Going ahead to step 3:
112 divided by 81 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 31 after subtracting 81 from 112.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 81

Going ahead to step 4:
81 can be fit into 319 3 times, resulting in a remainder of 76.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 243 from 319 leaves us with 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 81

Let's proceed to step 5:
81 can be fit into 764 9 times, resulting in a remainder of 35.
The next digit of our result is 9. 
Result so far: 139.0
If we subtract 729 from 764, we get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 81

Advancing to step 6:
81 can be fit into 358 4 times, resulting in a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1394.0
The remainder is 34 after subtracting 324 from 358.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 81

On to step 7:
81 goes into 345 4 times with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 13944.0
Subtracting 324 from 345 leaves us with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 81

Advancing to step 8:
81 can be fit into 211 2 times, resulting in a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 139442.0
Deduct 162 from 211 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
The number 81 fits into 490 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 139442.6
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
81 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 139442.6
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
81 goes into 400 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 139442.604
The remainder is 76 after subtracting 324 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
81 goes into 760 9 times with a remainder of 31.
The next digit of our result is 9. 
Result so far: 139442.6049
Deduct 729 from 760 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
When dividing 310 by 81, we get 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 139442.60493
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 14:
If we divide 670 by 81, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 139442.604938
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
When dividing 220 by 81, we get 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 139442.6049382
Subtracting 162 from 220 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 16:
When dividing 580 by 81, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 139442.60493827
Deduct 567 from 580 and we're left 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.

In conclusion, the division gives 139442.60493827 with a balance of 1.3e-08.
