We're dividing 203755 by 81 
The aim is to understand the frequency of 81 in 203755.

Let's proceed to step 1:
81 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 81

Advancing to step 2:
20 divided by 81 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 81

Advancing to step 3:
203 divided by 81 is 2 with a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 162 from 203 to get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 81

Going ahead to step 4:
The number 81 fits into 417 5 times, leaving a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 405 from 417 leaves us with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 81

Moving on to step 5:
If we divide 125 by 81, we get 1 and a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 251.0
Deduct 81 from 125 and we're left with 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 81

Moving on to step 6:
445 divided by 81 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 2515.0
If we take 405 away from 445, we end up 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.

Let's proceed to step 7:
If we divide 400 by 81, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 2515.4
If we subtract 324 from 400, we 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.

Going ahead to step 8:
When dividing 760 by 81, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 2515.49
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.

On to step 9:
When dividing 310 by 81, we get 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 2515.493
Deduct 243 from 310 and we're left 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 10:
670 divided by 81 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 2515.4938
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.

Advancing to step 11:
81 goes into 220 2 times with a remainder of 58.
The next digit of our result is 2. 
Result so far: 2515.49382
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.

Advancing to step 12:
The number 81 fits into 580 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 2515.493827
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.

Let's proceed to step 13:
130 divided by 81 is 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 2515.4938271
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.

Step 14:
When dividing 490 by 81, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 2515.49382716
If we subtract 486 from 490, we 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.

In conclusion, the division gives 2515.49382716 with a balance of 4e-09.
