We're dividing 1181473 by 81 
The aim is to understand the frequency of 81 in 1181473.

Going ahead to step 1:
1 divided by 81 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 81

Going ahead to step 2:
If we divide 11 by 81, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 81

Step 3:
When dividing 118 by 81, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 81 away from 118, we end up with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 81

Let's proceed to step 4:
If we divide 371 by 81, we get 4 and a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 324 from 371 leaves us with 47.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 81

Moving on to step 5:
When dividing 474 by 81, we get 5 with a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 145.0
Deduct 405 from 474 and we're left with 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 81

Let's proceed to step 6:
81 can be fit into 697 8 times, resulting in a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 1458.0
If we subtract 648 from 697, we get 49.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 81

Advancing to step 7:
493 divided by 81 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 14586.0
Deduct 486 from 493 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
81 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 14586.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
The number 81 fits into 700 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 14586.08
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
When dividing 520 by 81, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 14586.086
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 14586.0864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
When dividing 160 by 81, we get 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 14586.08641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 13:
When dividing 790 by 81, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 14586.086419
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
81 can be fit into 610 7 times, resulting in a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 14586.0864197
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 15:
When dividing 430 by 81, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 14586.08641975
Subtracting 405 from 430 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 14586.08641975 with a balance of 2.5e-08.
