81040143 ÷ 191 
We want to figure out the number of times 81040143 can be divided by 191.

Step 1:
The number 191 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 191

Going ahead to step 2:
If we divide 81 by 191, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (0) from the dividend after 81, then repeat: 810 / 191

Step 3:
When dividing 810 by 191, we get 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 46 after subtracting 764 from 810.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 191

Let's proceed to step 4:
191 can be fit into 464 2 times, resulting in a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 382 away from 464, we end up with 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 191

Let's proceed to step 5:
820 divided by 191 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 424.0
The remainder is 56 after subtracting 764 from 820.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 191

Step 6:
191 goes into 561 2 times with a remainder of 179.
The number 2 becomes the next digit in our result. 
Result so far: 4242.0
Subtract 382 from 561 to get 179.
Include the next digit (4) from the dividend after 179, then repeat: 1794 / 191

Going ahead to step 7:
191 can be fit into 1794 9 times, resulting in a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 42429.0
If we subtract 1719 from 1794, we get 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 191

On to step 8:
753 divided by 191 is 3 with a remainder of 180.
Use 3 as the next digit of our solution. 
Result so far: 424293.0
If we take 573 away from 753, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 9:
191 can be fit into 1800 9 times, resulting in a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 424293.9
Subtracting 1719 from 1800 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 10:
When dividing 810 by 191, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 424293.94
Subtracting 764 from 810 leaves us 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 11:
191 goes into 460 2 times with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 424293.942
Subtracting 382 from 460 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 12:
The number 191 fits into 780 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 424293.9424
If we subtract 764 from 780, 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.

Let's proceed to step 13:
160 divided by 191 is 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 424293.9424
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
If we divide 1600 by 191, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 424293.942408
The remainder is 72 after subtracting 1528 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 15:
191 can be fit into 720 3 times, resulting in a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 424293.9424083
Subtracting 573 from 720 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 16:
191 goes into 1470 7 times with a remainder of 133.
The next digit of our result is 7. 
Result so far: 424293.94240837
If we take 1337 away from 1470, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

In conclusion, the division gives 424293.94240837 with a balance of 1.33e-07.
