422126 ÷ 20 
Let's see how many times 20 fits into 422126.

On to step 1:
4 divided by 20 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 20

Step 2:
The number 20 fits into 42 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 40 from 42 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 20

Advancing to step 3:
If we divide 22 by 20, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 2 after subtracting 20 from 22.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 20

Moving on to step 4:
The number 20 fits into 21 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 211.0
The remainder is 1 after subtracting 20 from 21.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 20

Advancing to step 5:
20 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 2110.0
If we take 0 away from 12, we end up with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 20

Moving on to step 6:
If we divide 126 by 20, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 21106.0
If we take 120 away from 126, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 21106.3
If we subtract 60 from 60, 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.

On to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21106.3
Subtracting 0 from 0 leaves us 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.

Going ahead to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21106.3
If we take 0 away from 0, 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.

The quotient of the division is 21106.3, and the remainder is 0.0.
