We're dividing 871943 by 22 
Let's see how many times 22 fits into 871943.

Going ahead to step 1:
22 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 22

Moving on to step 2:
When dividing 87 by 22, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 66 from 87, we get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 22

Moving on to step 3:
211 divided by 22 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 13 after subtracting 198 from 211.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 22

Let's proceed to step 4:
22 goes into 139 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 396.0
If we subtract 132 from 139, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 22

Moving on to step 5:
22 can be fit into 74 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3963.0
Subtracting 66 from 74 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 22

Let's proceed to step 6:
22 goes into 83 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 39633.0
The remainder is 17 after subtracting 66 from 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
The number 22 fits into 170 7 times, leaving a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 39633.7
If we take 154 away from 170, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
When dividing 160 by 22, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 39633.77
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 39633.77 and a remainder of 0.006.
