We're dividing 402422 by 20 
Our goal is to divide 402422 by 20.

Let's proceed to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 20

Let's proceed to step 2:
20 goes into 40 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 20

Let's proceed to step 3:
2 divided by 20 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 2 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 20

Going ahead to step 4:
The number 20 fits into 24 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
Deduct 20 from 24 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 20

Going ahead to step 5:
When dividing 42 by 20, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2012.0
If we subtract 40 from 42, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 20

Let's proceed to step 6:
When dividing 22 by 20, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 20121.0
Deduct 20 from 22 and we're left with 2.
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:
When dividing 20 by 20, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 20121.1
If we take 20 away from 20, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20121.1
If we subtract 0 from 0, we 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.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20121.1
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 20121.1 with a remaining 0.0.
