We're dividing 493735 by 81 
The aim is to understand the frequency of 81 in 493735.

Going ahead to step 1:
81 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 81

Going ahead to step 2:
81 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 81

On to step 3:
81 can be fit into 493 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 486 from 493 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 81

Advancing to step 4:
The number 81 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 81

Going ahead to step 5:
When dividing 773 by 81, we get 9 with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 609.0
Subtract 729 from 773 to get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 81

On to step 6:
When dividing 445 by 81, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 6095.0
The remainder is 40 after subtracting 405 from 445.
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:
81 goes into 400 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 6095.4
The remainder is 76 after subtracting 324 from 400.
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:
760 divided by 81 is 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 6095.49
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 6095.493
If we take 243 away from 310, we end up 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.

Let's proceed to step 10:
If we divide 670 by 81, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 6095.4938
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
If we divide 220 by 81, we get 2 and a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 6095.49382
Subtracting 162 from 220 leaves us 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.

Step 12:
81 goes into 580 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 6095.493827
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.

Step 13:
The number 81 fits into 130 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 6095.4938271
Subtract 81 from 130 to get 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:
The number 81 fits into 490 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6095.49382716
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.

The final result is 6095.49382716 with a remainder of 4e-09.
