We're dividing 888522 by 81 
The aim is to understand the frequency of 81 in 888522.

Let's proceed to step 1:
The number 81 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 81

Step 2:
88 divided by 81 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 81 from 88 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 81

Advancing to step 3:
81 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 78, we get 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 81

Advancing to step 4:
If we divide 785 by 81, we get 9 and a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Deduct 729 from 785 and we're left with 56.
Append the next digit (2) from the dividend to 56 and continue with: 562 / 81

Advancing to step 5:
The number 81 fits into 562 6 times, leaving a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 1096.0
If we subtract 486 from 562, we get 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 81

Advancing to step 6:
The number 81 fits into 762 9 times, leaving a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 10969.0
If we take 729 away from 762, 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.

Going ahead to step 7:
330 divided by 81 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 10969.4
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.

On to step 8:
60 divided by 81 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 10969.4
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
81 can be fit into 600 7 times, resulting in a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 10969.407
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.

Going ahead to step 10:
When dividing 330 by 81, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 10969.4074
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.

On to step 11:
The number 81 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10969.4074
Subtract 0 from 60 to 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.

Moving on to step 12:
If we divide 600 by 81, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 10969.407407
Subtract 567 from 600 to 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.

Let's proceed to step 13:
The number 81 fits into 330 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 10969.4074074
Subtracting 324 from 330 leaves us 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.

Moving on to step 14:
If we divide 60 by 81, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10969.4074074
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.

The final outcome is 10969.4074074, with a leftover of 6e-08.
