396418 divided by 20 
We want to divide 396418 by 20.

Let's proceed to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 20

On to step 2:
If we divide 39 by 20, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 19 after subtracting 20 from 39.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 20

On to step 3:
196 divided by 20 is 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 16 after subtracting 180 from 196.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 20

On to step 4:
164 divided by 20 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
If we subtract 160 from 164, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 20

Let's proceed to step 5:
41 divided by 20 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1982.0
Subtract 40 from 41 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 20

Step 6:
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: 19820.0
Subtract 0 from 18 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
The number 20 fits into 180 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 19820.9
Subtract 180 from 180 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 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 19820.9
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 19820.9
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.

In conclusion, the division gives 19820.9 with a balance of 0.0.
