We look at the division of 81012449 by 11 
We want to figure out the number of times 81012449 can be divided by 11.

Advancing to step 1:
If we divide 8 by 11, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 11

Advancing to step 2:
11 goes into 81 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 7.0
If we take 77 away from 81, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 11

On to step 3:
40 divided by 11 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 73.0
Deduct 33 from 40 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 11

Moving on to step 4:
11 can be fit into 71 6 times, resulting in a remainder of 5.
The next digit of our result is 6. 
Result so far: 736.0
If we subtract 66 from 71, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 11

Moving on to step 5:
11 goes into 52 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 7364.0
The remainder is 8 after subtracting 44 from 52.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 11

Step 6:
The number 11 fits into 84 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 73647.0
The remainder is 7 after subtracting 77 from 84.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 11

Let's proceed to step 7:
The number 11 fits into 74 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 736476.0
The remainder is 8 after subtracting 66 from 74.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 11

Going ahead to step 8:
11 can be fit into 89 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 7364768.0
The remainder is 1 after subtracting 88 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
10 divided by 11 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7364768.0
Subtracting 0 from 10 leaves us 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.

Step 10:
When dividing 100 by 11, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 7364768.09
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
When dividing 10 by 11, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 7364768.09
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 11, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 7364768.0909
Subtract 99 from 100 to get 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:
The number 11 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 7364768.0909
Deduct 0 from 10 and we're left 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.

Let's proceed to step 14:
The number 11 fits into 100 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 7364768.090909
Subtracting 99 from 100 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.

Moving on to step 15:
10 divided by 11 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7364768.090909
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.

Moving on to step 16:
If we divide 100 by 11, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 7364768.09090909
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 7364768.09090909 with a balance of 1e-09.
