647550 divided by 20 
Our goal is to divide 647550 by 20.

Let's proceed to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 20

Moving on to step 2:
When dividing 64 by 20, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 20

Advancing to step 3:
The number 20 fits into 47 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 40 from 47 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 20

Advancing to step 4:
The number 20 fits into 75 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 323.0
Deduct 60 from 75 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 20

Moving on to step 5:
If we divide 155 by 20, we get 7 and a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 3237.0
If we subtract 140 from 155, we get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 20

Going ahead to step 6:
150 divided by 20 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 32377.0
Deduct 140 from 150 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.

Advancing to step 7:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 32377.5
Subtracting 100 from 100 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.

On to step 8:
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: 32377.5
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.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32377.5
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.

Our division results in 32377.5 with a remaining 0.0.
