We divide 409892 by 20
We want to divide 409892 by 20.

Step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 20

Going ahead to step 2:
When dividing 40 by 20, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 40 from 40 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 20

Advancing to step 3:
20 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 20

On to step 4:
If we divide 98 by 20, we get 4 and a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 204.0
Subtract 80 from 98 to get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 20

Advancing to step 5:
When dividing 189 by 20, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 2049.0
Subtract 180 from 189 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 20

Moving on to step 6:
20 can be fit into 92 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 20494.0
If we take 80 away from 92, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 20, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 20494.6
If we subtract 120 from 120, 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:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20494.6
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20494.6
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.

After the division, we end up with 20494.6 and a remainder of 0.0.
