640205 divided by 1 
Let's see how many times 1 fits into 640205.

Let's proceed to step 1:
When dividing 6 by 1, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 2:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 4 from 4, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Step 3:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 640.0
Subtract 0 from 0 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Going ahead to step 4:
1 goes into 2 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 6402.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

On to step 5:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 64020.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Going ahead to step 6:
5 divided by 1 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 640205.0
If we take 5 away from 5, 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.

Advancing to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 640205.0
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:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 640205.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 640205.0 with a remainder of 0.0.
