We look at the division of 421811 by 22 
Let's see how many times 22 fits into 421811.

Step 1:
The number 22 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 22

Let's proceed to step 2:
The number 22 fits into 42 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 20 after subtracting 22 from 42.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 22

Going ahead to step 3:
22 goes into 201 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 198 from 201 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 22

Moving on to step 4:
If we divide 38 by 22, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 191.0
If we subtract 22 from 38, we get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 22

Step 5:
When dividing 161 by 22, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1917.0
If we subtract 154 from 161, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 22

Step 6:
The number 22 fits into 71 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 19173.0
If we subtract 66 from 71, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
22 goes into 50 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 19173.2
Subtract 44 from 50 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.

Advancing to step 8:
The number 22 fits into 60 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 19173.22
Subtracting 44 from 60 leaves us 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.

After the division, we end up with 19173.22 and a remainder of 0.016.
