Let's divide 22125655 by 866
We're looking to find how many times 866 goes into 22125655.

Advancing to 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
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 866

Going ahead to step 2:
The number 866 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 866

Let's proceed to step 3:
866 goes into 221 0 times with a remainder of 221.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 221, we end up with 221.
Append the next digit (2) from the dividend to 221 and continue with: 2212 / 866

Advancing to step 4:
The number 866 fits into 2212 2 times, leaving a remainder of 480.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1732 from 2212 to get 480.
Bring next digit (5) of the dividend behind the 480 and repeat the process: 4805 / 866

Advancing to step 5:
If we divide 4805 by 866, we get 5 and a remainder of 475.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 4330 from 4805 and we're left with 475.
Include the next digit (6) from the dividend after 475, then repeat: 4756 / 866

On to step 6:
866 goes into 4756 5 times with a remainder of 426.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
Subtracting 4330 from 4756 leaves us with 426.
Take the next digit (5) from the dividend and append it to 426, then repeat: 4265 / 866

Moving on to step 7:
If we divide 4265 by 866, we get 4 and a remainder of 801.
Put 4 as the next digit of the answer. 
Result so far: 2554.0
Subtracting 3464 from 4265 leaves us with 801.
Append the next digit (5) from the dividend to 801 and continue with: 8015 / 866

Step 8:
866 goes into 8015 9 times with a remainder of 221.
Record the quotient 9 as the next digit in the result. 
Result so far: 25549.0
If we take 7794 away from 8015, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 9:
866 goes into 2210 2 times with a remainder of 478.
The next digit of our result is 2. 
Result so far: 25549.2
If we subtract 1732 from 2210, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 10:
866 goes into 4780 5 times with a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 25549.25
If we take 4330 away from 4780, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 11:
When dividing 4500 by 866, we get 5 with a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 25549.255
The remainder is 170 after subtracting 4330 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 25549.255 with a balance of 0.017.
