39532 ÷ 81 
The aim is to understand the frequency of 81 in 39532.

Going ahead to step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 81

Step 2:
When dividing 39 by 81, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 81

Step 3:
If we divide 395 by 81, we get 4 and a remainder of 71.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 324 from 395 leaves us with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 81

Moving on to step 4:
The number 81 fits into 713 8 times, leaving a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 648 away from 713, we end up with 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 81

On to step 5:
If we divide 652 by 81, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 488.0
The remainder is 4 after subtracting 648 from 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 6:
40 divided by 81 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 488.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 81, we get 4 and a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 488.04
Subtracting 324 from 400 leaves us 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 8:
When dividing 760 by 81, we get 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 488.049
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.

Moving on to step 9:
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: 488.0493
If we subtract 243 from 310, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
If we divide 670 by 81, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 488.04938
Deduct 648 from 670 and we're left 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.

On to step 11:
81 goes into 220 2 times with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 488.049382
The remainder is 58 after subtracting 162 from 220.
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 12:
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: 488.0493827
Subtract 567 from 580 to get 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 13:
130 divided by 81 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 488.04938271
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 488.04938271 with a remainder of 4.9e-08.
