We look at the division of 30575166 by 866 
We're looking to find how many times 866 goes into 30575166.

On to step 1:
3 divided by 866 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 866

Let's proceed to step 2:
866 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 866

Moving on to step 3:
866 goes into 305 0 times with a remainder of 305.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 305 leaves us with 305.
Include the next digit (7) from the dividend after 305, then repeat: 3057 / 866

Let's proceed to step 4:
3057 divided by 866 is 3 with a remainder of 459.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2598 from 3057, we get 459.
Bring next digit (5) of the dividend behind the 459 and repeat the process: 4595 / 866

Step 5:
866 can be fit into 4595 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 4330 from 4595 to get 265.
Include the next digit (1) from the dividend after 265, then repeat: 2651 / 866

Step 6:
866 goes into 2651 3 times with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 353.0
If we take 2598 away from 2651, we end up with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 866

Advancing to step 7:
536 divided by 866 is 0 with a remainder of 536.
Write down 0 as next digit of the result. 
Result so far: 3530.0
If we take 0 away from 536, we end up with 536.
Include the next digit (6) from the dividend after 536, then repeat: 5366 / 866

Going ahead to step 8:
The number 866 fits into 5366 6 times, leaving a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 35306.0
Subtracting 5196 from 5366 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 9:
1700 divided by 866 is 1 with a remainder of 834.
Put 1 as the next digit of the answer. 
Result so far: 35306.1
Deduct 866 from 1700 and we're left with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Let's proceed to step 10:
8340 divided by 866 is 9 with a remainder of 546.
Use 9 as the next digit of our solution. 
Result so far: 35306.19
Deduct 7794 from 8340 and we're left with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 11:
5460 divided by 866 is 6 with a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 35306.196
The remainder is 264 after subtracting 5196 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 12:
The number 866 fits into 2640 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 35306.1963
Subtract 2598 from 2640 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
866 goes into 420 0 times with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 35306.1963
The remainder is 420 after subtracting 0 from 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 14:
866 can be fit into 4200 4 times, resulting in a remainder of 736.
The number 4 becomes the next digit in our result. 
Result so far: 35306.196304
The remainder is 736 after subtracting 3464 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 15:
866 goes into 7360 8 times with a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 35306.1963048
The remainder is 432 after subtracting 6928 from 7360.
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 16:
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: 35306.19630484
If we subtract 3464 from 4320, we get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

The final result is 35306.19630484 with a remainder of 8.56e-07.
