We're dividing 553604 by 20 
We're looking to find how many times 20 goes into 553604.

Moving on to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 20

Moving on to step 2:
55 divided by 20 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 40 from 55 and we're left with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 20

Step 3:
20 can be fit into 153 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 13 after subtracting 140 from 153.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 20

On to step 4:
20 goes into 136 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 276.0
If we take 120 away from 136, we end up with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 20

Let's proceed to step 5:
160 divided by 20 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2768.0
Subtract 160 from 160 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 20

Moving on to step 6:
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: 27680.0
If we subtract 0 from 4, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 27680.2
Subtract 40 from 40 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.

Step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27680.2
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.

Step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27680.2
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.

In conclusion, the division gives 27680.2 with a balance of 0.0.
