We're dividing 31416613 by 866 
Our goal is to divide 31416613 by 866.

Going ahead to step 1:
The number 866 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 866

Let's proceed to step 2:
31 divided by 866 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 866

Let's proceed to step 3:
The number 866 fits into 314 0 times, leaving a remainder of 314.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 314 to get 314.
Bring next digit (1) of the dividend behind the 314 and repeat the process: 3141 / 866

Moving on to step 4:
If we divide 3141 by 866, we get 3 and a remainder of 543.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 2598 from 3141 to get 543.
Grab the next digit (6) from the dividend, add it to 543, then carry on: 5436 / 866

Going ahead to step 5:
5436 divided by 866 is 6 with a remainder of 240.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 5196 from 5436 to get 240.
Grab the next digit (6) from the dividend, add it to 240, then carry on: 2406 / 866

Step 6:
866 goes into 2406 2 times with a remainder of 674.
Write down 2 as next digit of the result. 
Result so far: 362.0
If we take 1732 away from 2406, we end up with 674.
Include the next digit (1) from the dividend after 674, then repeat: 6741 / 866

Moving on to step 7:
866 goes into 6741 7 times with a remainder of 679.
The next digit of our result is 7. 
Result so far: 3627.0
Deduct 6062 from 6741 and we're left with 679.
Fetch the next digit (3) from the dividend, attach it to 679 and continue: 6793 / 866

Let's proceed to step 8:
6793 divided by 866 is 7 with a remainder of 731.
The number 7 becomes the next digit in our result. 
Result so far: 36277.0
Subtracting 6062 from 6793 leaves us with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

On to step 9:
The number 866 fits into 7310 8 times, leaving a remainder of 382.
Record the quotient 8 as the next digit in the result. 
Result so far: 36277.8
If we subtract 6928 from 7310, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 10:
866 can be fit into 3820 4 times, resulting in a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 36277.84
Subtracting 3464 from 3820 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 11:
866 can be fit into 3560 4 times, resulting in a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 36277.844
Deduct 3464 from 3560 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 36277.844 and a remainder of 0.0096.
