911026 divided by 81 
The aim is to understand the frequency of 81 in 911026.

Advancing to step 1:
When dividing 9 by 81, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 81

Step 2:
The number 81 fits into 91 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 81 from 91 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 81

Moving on to step 3:
81 can be fit into 101 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 81 from 101 and we're left with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 81

Going ahead to step 4:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we subtract 162 from 200, we get 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 81

Step 5:
If we divide 382 by 81, we get 4 and a remainder of 58.
The next digit of our result is 4. 
Result so far: 1124.0
If we take 324 away from 382, we end up with 58.
Fetch the next digit (6) from the dividend, attach it to 58 and continue: 586 / 81

Moving on to step 6:
If we divide 586 by 81, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 11247.0
Subtract 567 from 586 to 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.

On to step 7:
190 divided by 81 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 11247.2
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 8:
If we divide 280 by 81, we get 3 and a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 11247.23
Subtract 243 from 280 to 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 9:
370 divided by 81 is 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 11247.234
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
When dividing 460 by 81, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 11247.2345
If we take 405 away from 460, we end up 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.

Step 11:
81 can be fit into 550 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 11247.23456
Subtract 486 from 550 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
640 divided by 81 is 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 11247.234567
If we take 567 away from 640, we end up with 73.
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 13:
If we divide 730 by 81, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 11247.2345679
Subtracting 729 from 730 leaves us 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 14:
10 divided by 81 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 11247.2345679
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 11247.2345679 and a remainder of 1e-08.
