We're dividing 65996042 by 640 
We want to figure out the number of times 65996042 can be divided by 640.

Going ahead to step 1:
When dividing 6 by 640, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 640

Advancing to step 2:
The number 640 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 640

Step 3:
If we divide 659 by 640, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 640 from 659, we get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 640

Moving on to step 4:
199 divided by 640 is 0 with a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 199 after subtracting 0 from 199.
Bring next digit (6) of the dividend behind the 199 and repeat the process: 1996 / 640

Moving on to step 5:
1996 divided by 640 is 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we subtract 1920 from 1996, we get 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 640

On to step 6:
The number 640 fits into 760 1 times, leaving a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 1031.0
Deduct 640 from 760 and we're left with 120.
Take the next digit (4) from the dividend and append it to 120, then repeat: 1204 / 640

Going ahead to step 7:
When dividing 1204 by 640, we get 1 with a remainder of 564.
The number 1 becomes the next digit in our result. 
Result so far: 10311.0
Subtract 640 from 1204 to get 564.
Append the next digit (2) from the dividend to 564 and continue with: 5642 / 640

Going ahead to step 8:
5642 divided by 640 is 8 with a remainder of 522.
The next digit of our result is 8. 
Result so far: 103118.0
Deduct 5120 from 5642 and we're left with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 9:
The number 640 fits into 5220 8 times, leaving a remainder of 100.
Write down 8 as next digit of the result. 
Result so far: 103118.8
Subtracting 5120 from 5220 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
The number 640 fits into 1000 1 times, leaving a remainder of 360.
Write down 1 as next digit of the result. 
Result so far: 103118.81
If we subtract 640 from 1000, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
640 can be fit into 3600 5 times, resulting in a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 103118.815
Subtracting 3200 from 3600 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
4000 divided by 640 is 6 with a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 103118.8156
If we subtract 3840 from 4000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
If we divide 1600 by 640, we get 2 and a remainder of 320.
The next digit of our result is 2. 
Result so far: 103118.81562
Deduct 1280 from 1600 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
If we divide 3200 by 640, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 103118.815625
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.

On to step 15:
640 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 103118.815625
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.

Step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 103118.815625
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.

The final result is 103118.815625 with a remainder of 0.0.
