281047 divided by 81 
The aim is to understand the frequency of 81 in 281047.

Advancing to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 81

Advancing to step 2:
If we divide 28 by 81, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 81

Moving on to step 3:
If we divide 281 by 81, we get 3 and a remainder of 38.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 243 from 281, we get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 81

Let's proceed to step 4:
81 goes into 380 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 324 from 380, we get 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 81

Advancing to step 5:
81 goes into 564 6 times with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 346.0
The remainder is 78 after subtracting 486 from 564.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 81

Step 6:
81 can be fit into 787 9 times, resulting in a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 3469.0
Deduct 729 from 787 and we're left 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 7:
If we divide 580 by 81, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 3469.7
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.

Let's proceed to step 8:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 3469.71
If we take 81 away from 130, we end up 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.

Moving on to step 9:
490 divided by 81 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3469.716
Deduct 486 from 490 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 81, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3469.716
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.

Moving on to step 11:
The number 81 fits into 400 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 3469.71604
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
81 can be fit into 760 9 times, resulting in a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 3469.716049
If we take 729 away from 760, we end up 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.

Step 13:
If we divide 310 by 81, we get 3 and a remainder of 67.
The next digit of our result is 3. 
Result so far: 3469.7160493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

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: 3469.71604938
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 3469.71604938 and a remainder of 2.2e-08.
