408056 divided by 20 
Let's see how many times 20 fits into 408056.

Going ahead to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 20

On to step 2:
40 divided by 20 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 0 after subtracting 40 from 40.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 20

Let's proceed to step 3:
If we divide 8 by 20, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 20

Advancing to step 4:
If we divide 80 by 20, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 204.0
If we take 80 away from 80, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 20

Step 5:
When dividing 5 by 20, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 2040.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 20

Advancing to step 6:
20 goes into 56 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 20402.0
The remainder is 16 after subtracting 40 from 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
20 can be fit into 160 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 20402.8
Deduct 160 from 160 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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20402.8
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.

Advancing to step 9:
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: 20402.8
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.

In conclusion, the division gives 20402.8 with a balance of 0.0.
