We divide 96579820 by 640
Our goal is to divide 96579820 by 640.

On to step 1:
The number 640 fits into 9 0 times, leaving 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.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 640

Going ahead to step 2:
When dividing 96 by 640, we get 0 with a remainder of 96.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 96, we get 96.
Bring next digit (5) of the dividend behind the 96 and repeat the process: 965 / 640

On to step 3:
When dividing 965 by 640, we get 1 with a remainder of 325.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 640 from 965 to get 325.
Fetch the next digit (7) from the dividend, attach it to 325 and continue: 3257 / 640

On to step 4:
If we divide 3257 by 640, we get 5 and a remainder of 57.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 3200 from 3257, we get 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 640

Moving on to step 5:
If we divide 579 by 640, we get 0 and a remainder of 579.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtracting 0 from 579 leaves us with 579.
Append the next digit (8) from the dividend to 579 and continue with: 5798 / 640

On to step 6:
If we divide 5798 by 640, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 1509.0
Subtracting 5760 from 5798 leaves us with 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 640

Going ahead to step 7:
The number 640 fits into 382 0 times, leaving a remainder of 382.
The number 0 becomes the next digit in our result. 
Result so far: 15090.0
Subtracting 0 from 382 leaves us with 382.
Bring next digit (0) of the dividend behind the 382 and repeat the process: 3820 / 640

Step 8:
640 can be fit into 3820 5 times, resulting in a remainder of 620.
The next digit of our result is 5. 
Result so far: 150905.0
The remainder is 620 after subtracting 3200 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 9:
640 goes into 6200 9 times with a remainder of 440.
Write down 9 as next digit of the result. 
Result so far: 150905.9
Deduct 5760 from 6200 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 10:
4400 divided by 640 is 6 with a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 150905.96
Subtract 3840 from 4400 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 11:
640 goes into 5600 8 times with a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 150905.968
Deduct 5120 from 5600 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 12:
4800 divided by 640 is 7 with a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 150905.9687
If we subtract 4480 from 4800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 150905.96875
If we subtract 3200 from 3200, we 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.

Going ahead to step 14:
When dividing 0 by 640, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 150905.96875
If we subtract 0 from 0, we 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.

Advancing to step 15:
640 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 150905.96875
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.

After the division, we end up with 150905.96875 and a remainder of 0.0.
