We look at the division of 546853 by 81 
The aim is to understand the frequency of 81 in 546853.

On to step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 81

On to step 2:
If we divide 54 by 81, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 81

Advancing to step 3:
546 divided by 81 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 486 from 546 to get 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 81

Let's proceed to step 4:
81 goes into 608 7 times with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we subtract 567 from 608, we get 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 81

Moving on to step 5:
When dividing 415 by 81, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 675.0
If we take 405 away from 415, we end up with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 81

Going ahead to step 6:
81 can be fit into 103 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 6751.0
If we take 81 away from 103, we end up 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.

Let's proceed to step 7:
If we divide 220 by 81, we get 2 and a remainder of 58.
The next digit of our result is 2. 
Result so far: 6751.2
Subtract 162 from 220 to get 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 8:
If we divide 580 by 81, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 6751.27
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.

Advancing to step 9:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 6751.271
Subtracting 81 from 130 leaves us 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.

Advancing to step 10:
If we divide 490 by 81, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6751.2716
If we take 486 away from 490, we end up with 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 11:
When dividing 40 by 81, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6751.2716
Subtracting 0 from 40 leaves us 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.

Going ahead to step 12:
81 can be fit into 400 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 6751.271604
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.

On to step 13:
81 goes into 760 9 times with a remainder of 31.
The next digit of our result is 9. 
Result so far: 6751.2716049
Deduct 729 from 760 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
If we divide 310 by 81, we get 3 and a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 6751.27160493
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

In conclusion, the division gives 6751.27160493 with a balance of 6.7e-08.
