39563 divided by 20 
Our goal is to divide 39563 by 20.

Advancing to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
The next digit of our result is 0. 
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

Let's proceed to step 2:
When dividing 39 by 20, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
If we take 20 away from 39, we end up with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 20

Step 3:
If we divide 195 by 20, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 180 from 195 leaves us with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 20

Going ahead to step 4:
The number 20 fits into 156 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 197.0
The remainder is 16 after subtracting 140 from 156.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 20

Going ahead to step 5:
If we divide 163 by 20, we get 8 and a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 1978.0
If we subtract 160 from 163, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1978.1
Deduct 20 from 30 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1978.15
If we subtract 100 from 100, 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.
Put 0 as the next digit of the answer. 
Result so far: 1978.15
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.

Step 9:
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: 1978.15
Subtract 0 from 0 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.

Our division results in 1978.15 with a remaining 0.0.
