We look at the division of 663975 by 65 
Let's see how many times 65 fits into 663975.

On to step 1:
65 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 65

Going ahead to step 2:
When dividing 66 by 65, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 65 from 66.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 65

Step 3:
When dividing 13 by 65, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 65

Step 4:
The number 65 fits into 139 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtract 130 from 139 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 65

Going ahead to step 5:
97 divided by 65 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1021.0
Subtract 65 from 97 to get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 65

Step 6:
The number 65 fits into 325 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10215.0
Deduct 325 from 325 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.

Going ahead to step 7:
If we divide 0 by 65, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10215.0
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.

Let's proceed to step 8:
65 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10215.0
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 10215.0 with a balance of 0.0.
