We divide 640203 by 10
Our goal is to divide 640203 by 10.

Advancing to step 1:
The number 10 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
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 / 10

Moving on to step 2:
10 goes into 64 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
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 / 10

Moving on to step 3:
If we divide 40 by 10, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 0 after subtracting 40 from 40.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 10

Let's proceed to step 4:
When dividing 2 by 10, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 640.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 10

Step 5:
When dividing 20 by 10, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 6402.0
The remainder is 0 after subtracting 20 from 20.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 10

Let's proceed to step 6:
3 divided by 10 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 64020.0
Deduct 0 from 3 and we're left with 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 7:
30 divided by 10 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 64020.3
The remainder is 0 after subtracting 30 from 30.
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:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 64020.3
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.

Moving on to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 64020.3
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 64020.3 with a balance of 0.0.
