We're dividing 81453782 by 866 
Let's see how many times 866 fits into 81453782.

Let's proceed to step 1:
866 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 866

Advancing to step 2:
If we divide 81 by 866, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 866

On to step 3:
814 divided by 866 is 0 with a remainder of 814.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 814 to get 814.
Append the next digit (5) from the dividend to 814 and continue with: 8145 / 866

Advancing to step 4:
If we divide 8145 by 866, we get 9 and a remainder of 351.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 7794 away from 8145, we end up with 351.
Include the next digit (3) from the dividend after 351, then repeat: 3513 / 866

Step 5:
When dividing 3513 by 866, we get 4 with a remainder of 49.
The next digit of our result is 4. 
Result so far: 94.0
If we subtract 3464 from 3513, we get 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 866

Going ahead to step 6:
If we divide 497 by 866, we get 0 and a remainder of 497.
The next digit of our result is 0. 
Result so far: 940.0
Subtract 0 from 497 to get 497.
Grab the next digit (8) from the dividend, add it to 497, then carry on: 4978 / 866

Let's proceed to step 7:
4978 divided by 866 is 5 with a remainder of 648.
The number 5 becomes the next digit in our result. 
Result so far: 9405.0
Deduct 4330 from 4978 and we're left with 648.
Append the next digit (2) from the dividend to 648 and continue with: 6482 / 866

Advancing to step 8:
866 can be fit into 6482 7 times, resulting in a remainder of 420.
Write down 7 as next digit of the result. 
Result so far: 94057.0
If we subtract 6062 from 6482, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 9:
4200 divided by 866 is 4 with a remainder of 736.
Write down 4 as next digit of the result. 
Result so far: 94057.4
If we subtract 3464 from 4200, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 10:
When dividing 7360 by 866, we get 8 with a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 94057.48
Subtract 6928 from 7360 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 11:
866 can be fit into 4320 4 times, resulting in a remainder of 856.
Use 4 as the next digit of our solution. 
Result so far: 94057.484
The remainder is 856 after subtracting 3464 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 12:
The number 866 fits into 8560 9 times, leaving a remainder of 766.
Write down 9 as next digit of the result. 
Result so far: 94057.4849
If we take 7794 away from 8560, we end up with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Going ahead to step 13:
If we divide 7660 by 866, we get 8 and a remainder of 732.
Use 8 as the next digit of our solution. 
Result so far: 94057.48498
Subtract 6928 from 7660 to get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Let's proceed to step 14:
866 goes into 7320 8 times with a remainder of 392.
Put 8 as the next digit of the answer. 
Result so far: 94057.484988
Subtract 6928 from 7320 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final result is 94057.484988 with a remainder of 3.92e-05.
