Let's divide 19727 by 81
The aim is to understand the frequency of 81 in 19727.

Advancing to step 1:
81 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 81

Let's proceed to step 2:
The number 81 fits into 19 0 times, leaving a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 81

Going ahead to step 3:
The number 81 fits into 197 2 times, leaving a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 162 from 197 leaves us with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 81

Advancing to step 4:
81 goes into 352 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 324 from 352 and we're left with 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 81

Going ahead to step 5:
81 goes into 287 3 times with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
Subtracting 243 from 287 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 6:
The number 81 fits into 440 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 243.5
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
81 goes into 350 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 243.54
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
When dividing 260 by 81, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 243.543
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
170 divided by 81 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 243.5432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 81, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 243.5432
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
When dividing 800 by 81, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 243.543209
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 12:
81 can be fit into 710 8 times, resulting in a remainder of 62.
The next digit of our result is 8. 
Result so far: 243.5432098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
If we divide 620 by 81, we get 7 and a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 243.54320987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 243.54320987, and the remainder is 5.3e-08.
