We're dividing 111165 by 81 
The aim is to understand the frequency of 81 in 111165.

Let's proceed to step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 81

Step 2:
The number 81 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 81

Moving on to step 3:
81 can be fit into 111 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 111, we end up with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 81

Going ahead to step 4:
81 goes into 301 3 times with a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 243 away from 301, we end up with 58.
Grab the next digit (6) from the dividend, add it to 58, then carry on: 586 / 81

Advancing to step 5:
586 divided by 81 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Subtract 567 from 586 to get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 81

Step 6:
81 goes into 195 2 times with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 1372.0
If we take 162 away from 195, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
When dividing 330 by 81, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 1372.4
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 81 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1372.4
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
81 can be fit into 600 7 times, resulting in a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 1372.407
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 10:
If we divide 330 by 81, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1372.4074
If we subtract 324 from 330, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
60 divided by 81 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1372.4074
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
81 goes into 600 7 times with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 1372.407407
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
81 goes into 330 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1372.4074074
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
When dividing 60 by 81, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 1372.4074074
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 1372.4074074 with a balance of 6e-08.
