We're dividing 97596303 by 640 
We want to figure out the number of times 97596303 can be divided by 640.

Advancing to step 1:
When dividing 9 by 640, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 640

Advancing to step 2:
When dividing 97 by 640, we get 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Grab the next digit (5) from the dividend, add it to 97, then carry on: 975 / 640

Going ahead to step 3:
640 can be fit into 975 1 times, resulting in a remainder of 335.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 640 away from 975, we end up with 335.
Take the next digit (9) from the dividend and append it to 335, then repeat: 3359 / 640

Let's proceed to step 4:
The number 640 fits into 3359 5 times, leaving a remainder of 159.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 3200 from 3359 to get 159.
Include the next digit (6) from the dividend after 159, then repeat: 1596 / 640

Let's proceed to step 5:
The number 640 fits into 1596 2 times, leaving a remainder of 316.
Write down 2 as next digit of the result. 
Result so far: 152.0
The remainder is 316 after subtracting 1280 from 1596.
Bring next digit (3) of the dividend behind the 316 and repeat the process: 3163 / 640

Step 6:
640 goes into 3163 4 times with a remainder of 603.
Write down 4 as next digit of the result. 
Result so far: 1524.0
The remainder is 603 after subtracting 2560 from 3163.
Take the next digit (0) from the dividend and append it to 603, then repeat: 6030 / 640

Going ahead to step 7:
When dividing 6030 by 640, we get 9 with a remainder of 270.
Write down 9 as next digit of the result. 
Result so far: 15249.0
Subtracting 5760 from 6030 leaves us with 270.
Include the next digit (3) from the dividend after 270, then repeat: 2703 / 640

Step 8:
If we divide 2703 by 640, we get 4 and a remainder of 143.
Put 4 as the next digit of the answer. 
Result so far: 152494.0
If we take 2560 away from 2703, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 9:
When dividing 1430 by 640, we get 2 with a remainder of 150.
The number 2 becomes the next digit in our result. 
Result so far: 152494.2
The remainder is 150 after subtracting 1280 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
The number 640 fits into 1500 2 times, leaving a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 152494.22
Deduct 1280 from 1500 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 152494.22 with a balance of 0.22.
