2222859 divided by 866 
Let's see how many times 866 fits into 2222859.

Step 1:
866 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 866

Let's proceed to step 2:
866 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 866

Advancing to step 3:
866 goes into 222 0 times with a remainder of 222.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 222 to get 222.
Grab the next digit (2) from the dividend, add it to 222, then carry on: 2222 / 866

Going ahead to step 4:
2222 divided by 866 is 2 with a remainder of 490.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1732 from 2222 and we're left with 490.
Bring next digit (8) of the dividend behind the 490 and repeat the process: 4908 / 866

Going ahead to step 5:
4908 divided by 866 is 5 with a remainder of 578.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 4330 from 4908 and we're left with 578.
Take the next digit (5) from the dividend and append it to 578, then repeat: 5785 / 866

Moving on to step 6:
When dividing 5785 by 866, we get 6 with a remainder of 589.
Use 6 as the next digit of our solution. 
Result so far: 256.0
If we subtract 5196 from 5785, we get 589.
Take the next digit (9) from the dividend and append it to 589, then repeat: 5899 / 866

Moving on to step 7:
When dividing 5899 by 866, we get 6 with a remainder of 703.
Record the quotient 6 as the next digit in the result. 
Result so far: 2566.0
The remainder is 703 after subtracting 5196 from 5899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Step 8:
866 can be fit into 7030 8 times, resulting in a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 2566.8
Subtracting 6928 from 7030 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
The number 866 fits into 1020 1 times, leaving a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 2566.81
Deduct 866 from 1020 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 10:
When dividing 1540 by 866, we get 1 with a remainder of 674.
The number 1 becomes the next digit in our result. 
Result so far: 2566.811
If we subtract 866 from 1540, we get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

The quotient of the division is 2566.811, and the remainder is 0.0674.
