109882 divided by 81 
The aim is to understand the frequency of 81 in 109882.

Moving on to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 81

On to step 2:
10 divided by 81 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 81

Let's proceed to step 3:
81 can be fit into 109 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 28 after subtracting 81 from 109.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 81

Going ahead to step 4:
288 divided by 81 is 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 243 from 288 and we're left with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 81

Step 5:
If we divide 458 by 81, we get 5 and a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 135.0
Subtract 405 from 458 to get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 81

Step 6:
532 divided by 81 is 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 1356.0
Subtracting 486 from 532 leaves us 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 7:
The number 81 fits into 460 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 1356.5
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
If we divide 550 by 81, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1356.56
Subtracting 486 from 550 leaves us 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 9:
When dividing 640 by 81, we get 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 1356.567
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 10:
If we divide 730 by 81, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1356.5679
Subtract 729 from 730 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
If we divide 10 by 81, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1356.5679
Subtract 0 from 10 to 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 12:
If we divide 100 by 81, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1356.567901
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.

Let's proceed to step 13:
190 divided by 81 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1356.5679012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
The number 81 fits into 280 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 1356.56790123
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.

After the division, we end up with 1356.56790123 and a remainder of 3.7e-08.
