We're dividing 841456 by 81 
The aim is to understand the frequency of 81 in 841456.

Advancing to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 81

On to step 2:
81 goes into 84 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 81 from 84 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 81

Going ahead to step 3:
If we divide 31 by 81, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 31, we get 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 81

On to step 4:
If we divide 314 by 81, we get 3 and a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 243 from 314 to get 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 81

Let's proceed to step 5:
81 can be fit into 715 8 times, resulting in a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 1038.0
If we subtract 648 from 715, we get 67.
Append the next digit (6) from the dividend to 67 and continue with: 676 / 81

Let's proceed to step 6:
81 goes into 676 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 10388.0
The remainder is 28 after subtracting 648 from 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
280 divided by 81 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 10388.3
If we take 243 away from 280, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 10388.34
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
When dividing 460 by 81, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 10388.345
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
When dividing 550 by 81, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 10388.3456
If we take 486 away from 550, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
81 goes into 640 7 times with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 10388.34567
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 12:
81 can be fit into 730 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 10388.345679
The remainder is 1 after subtracting 729 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
If we divide 10 by 81, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10388.345679
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
81 can be fit into 100 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 10388.34567901
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 10388.34567901 with a remaining 1.9e-08.
