16384 ÷ 81 
The aim is to understand the frequency of 81 in 16384.

Going ahead to step 1:
81 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 81

Advancing to step 2:
16 divided by 81 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 81

Going ahead to step 3:
If we divide 163 by 81, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 162 from 163 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 81

Going ahead to step 4:
When dividing 18 by 81, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 81

On to step 5:
The number 81 fits into 184 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
Subtracting 162 from 184 leaves us 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 6:
220 divided by 81 is 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 202.2
Deduct 162 from 220 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.

Moving on to step 7:
When dividing 580 by 81, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 202.27
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.

On to step 8:
When dividing 130 by 81, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 202.271
Deduct 81 from 130 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.

On to step 9:
490 divided by 81 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 202.2716
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.

Advancing to step 10:
If we divide 40 by 81, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 202.2716
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

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: 202.271604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
81 goes into 760 9 times with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 202.2716049
Subtract 729 from 760 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
The number 81 fits into 310 3 times, leaving a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 202.27160493
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.

The final result is 202.27160493 with a remainder of 6.7e-08.
