We look at the division of 618422 by 20 
Let's see how many times 20 fits into 618422.

Step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 20

Step 2:
The number 20 fits into 61 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 60 from 61, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 20

Step 3:
The number 20 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 18 to get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 20

Let's proceed to step 4:
20 can be fit into 184 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 309.0
Subtract 180 from 184 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 20

Going ahead to step 5:
42 divided by 20 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 3092.0
If we take 40 away from 42, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 20

On to step 6:
When dividing 22 by 20, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 30921.0
The remainder is 2 after subtracting 20 from 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 can be fit into 20 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 30921.1
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30921.1
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30921.1
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 30921.1 and a remainder of 0.0.
