We look at the division of 200640 by 20 
We want to figure out the number of times 200640 can be divided by 20.

Advancing to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 20

Let's proceed to step 2:
20 goes into 20 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 20 from 20 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 20

Advancing to step 3:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 20

On to step 4:
6 divided by 20 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 20

Moving on to step 5:
If we divide 64 by 20, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1003.0
If we take 60 away from 64, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 20

Step 6:
When dividing 40 by 20, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 10032.0
If we take 40 away from 40, 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.

On to step 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10032.0
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.

Let's proceed to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10032.0
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.

In conclusion, the division gives 10032.0 with a balance of 0.0.
