We look at the division of 267490 by 81 
The aim is to understand the frequency of 81 in 267490.

Going ahead to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 81

Moving on to step 2:
If we divide 26 by 81, we get 0 and a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 81

On to step 3:
When dividing 267 by 81, we get 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 243 away from 267, we end up with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 81

Going ahead to step 4:
81 goes into 244 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 243 from 244 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 81

Moving on to step 5:
81 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 330.0
If we take 0 away from 19, we end up with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 81

Step 6:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 3302.0
Subtract 162 from 190 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
81 can be fit into 280 3 times, resulting in a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 3302.3
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
The number 81 fits into 370 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 3302.34
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
460 divided by 81 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 3302.345
Subtracting 405 from 460 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
81 goes into 550 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3302.3456
Deduct 486 from 550 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
If we divide 640 by 81, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 3302.34567
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 12:
If we divide 730 by 81, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 3302.345679
Deduct 729 from 730 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
81 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3302.345679
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 81 fits into 100 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 3302.34567901
If we subtract 81 from 100, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 3302.34567901 with a balance of 1.9e-08.
