We look at the division of 69349 by 81 
The aim is to understand the frequency of 81 in 69349.

Let's proceed to step 1:
When dividing 6 by 81, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 81

On to step 2:
If we divide 69 by 81, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 81

Step 3:
81 goes into 693 8 times with a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 648 from 693 to get 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 81

Let's proceed to step 4:
When dividing 454 by 81, we get 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 405 from 454 leaves us with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 81

On to step 5:
81 goes into 499 6 times with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 856.0
The remainder is 13 after subtracting 486 from 499.
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 6:
130 divided by 81 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 856.1
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.

Moving on to step 7:
When dividing 490 by 81, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 856.16
Deduct 486 from 490 and we're left 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 8:
40 divided by 81 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 856.16
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.

On to step 9:
When dividing 400 by 81, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 856.1604
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 10:
760 divided by 81 is 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 856.16049
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.

Going ahead to step 11:
When dividing 310 by 81, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 856.160493
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 12:
The number 81 fits into 670 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 856.1604938
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 13:
220 divided by 81 is 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 856.16049382
If we take 162 away from 220, we end up 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.

The final result is 856.16049382 with a remainder of 5.8e-08.
