Let's divide 80804079 by 640
We want to figure out the number of times 80804079 can be divided by 640.

Let's proceed to step 1:
When dividing 8 by 640, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 640

Going ahead to step 2:
640 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 640

Moving on to step 3:
640 goes into 808 1 times with a remainder of 168.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 168 after subtracting 640 from 808.
Fetch the next digit (0) from the dividend, attach it to 168 and continue: 1680 / 640

Going ahead to step 4:
640 can be fit into 1680 2 times, resulting in a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1280 from 1680, we get 400.
Grab the next digit (4) from the dividend, add it to 400, then carry on: 4004 / 640

On to step 5:
The number 640 fits into 4004 6 times, leaving a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtract 3840 from 4004 to get 164.
Grab the next digit (0) from the dividend, add it to 164, then carry on: 1640 / 640

Going ahead to step 6:
When dividing 1640 by 640, we get 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 1262.0
Deduct 1280 from 1640 and we're left with 360.
Grab the next digit (7) from the dividend, add it to 360, then carry on: 3607 / 640

On to step 7:
The number 640 fits into 3607 5 times, leaving a remainder of 407.
Put 5 as the next digit of the answer. 
Result so far: 12625.0
Deduct 3200 from 3607 and we're left with 407.
Append the next digit (9) from the dividend to 407 and continue with: 4079 / 640

Advancing to step 8:
640 goes into 4079 6 times with a remainder of 239.
The number 6 becomes the next digit in our result. 
Result so far: 126256.0
The remainder is 239 after subtracting 3840 from 4079.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 9:
2390 divided by 640 is 3 with a remainder of 470.
The number 3 becomes the next digit in our result. 
Result so far: 126256.3
The remainder is 470 after subtracting 1920 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 10:
640 goes into 4700 7 times with a remainder of 220.
Record the quotient 7 as the next digit in the result. 
Result so far: 126256.37
The remainder is 220 after subtracting 4480 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
640 goes into 2200 3 times with a remainder of 280.
The number 3 becomes the next digit in our result. 
Result so far: 126256.373
Subtracting 1920 from 2200 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
640 can be fit into 2800 4 times, resulting in a remainder of 240.
The next digit of our result is 4. 
Result so far: 126256.3734
The remainder is 240 after subtracting 2560 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
If we divide 2400 by 640, we get 3 and a remainder of 480.
The next digit of our result is 3. 
Result so far: 126256.37343
If we subtract 1920 from 2400, we get 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 14:
When dividing 4800 by 640, we get 7 with a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 126256.373437
Subtracting 4480 from 4800 leaves us 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.

Let's proceed to step 15:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 126256.3734375
Subtract 3200 from 3200 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.

Step 16:
0 divided by 640 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 126256.3734375
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.

In conclusion, the division gives 126256.3734375 with a balance of 0.0.
