We look at the division of 20909 by 63 
We're looking to find how many times 63 goes into 20909.

On to step 1:
The number 63 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 63

Going ahead to step 2:
If we divide 20 by 63, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 63

Step 3:
209 divided by 63 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 189 from 209, we get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 63

Moving on to step 4:
200 divided by 63 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Deduct 189 from 200 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 63

Advancing to step 5:
The number 63 fits into 119 1 times, leaving a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 331.0
The remainder is 56 after subtracting 63 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 6:
If we divide 560 by 63, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 331.8
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
63 goes into 560 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 331.88
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 331.88 with a balance of 0.056.
