We're dividing 866891 by 22 
We want to divide 866891 by 22.

On to step 1:
When dividing 8 by 22, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 22

Step 2:
The number 22 fits into 86 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 66 away from 86, we end up with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 22

On to step 3:
22 goes into 206 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 198 from 206, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 22

Moving on to step 4:
88 divided by 22 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 394.0
Deduct 88 from 88 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 22

Going ahead to step 5:
The number 22 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 3940.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 22

On to step 6:
When dividing 91 by 22, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 39404.0
Subtracting 88 from 91 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 22 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 39404.1
If we take 22 away from 30, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
80 divided by 22 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 39404.13
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
22 goes into 140 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 39404.136
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
80 divided by 22 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 39404.1363
Subtract 66 from 80 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
22 goes into 140 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 39404.13636
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
80 divided by 22 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 39404.136363
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
140 divided by 22 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 39404.1363636
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
22 goes into 80 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 39404.13636363
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 39404.13636363 with a remainder of 1.4e-08.
