We're dividing 79680264 by 640 
We want to figure out the number of times 79680264 can be divided by 640.

Let's proceed to step 1:
7 divided by 640 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 640

Let's proceed to step 2:
The number 640 fits into 79 0 times, leaving a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Take the next digit (6) from the dividend and append it to 79, then repeat: 796 / 640

Let's proceed to step 3:
640 can be fit into 796 1 times, resulting in a remainder of 156.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 640 from 796 leaves us with 156.
Grab the next digit (8) from the dividend, add it to 156, then carry on: 1568 / 640

Let's proceed to step 4:
1568 divided by 640 is 2 with a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 288 after subtracting 1280 from 1568.
Append the next digit (0) from the dividend to 288 and continue with: 2880 / 640

Advancing to step 5:
2880 divided by 640 is 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we take 2560 away from 2880, we end up with 320.
Append the next digit (2) from the dividend to 320 and continue with: 3202 / 640

Let's proceed to step 6:
3202 divided by 640 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 1245.0
Subtract 3200 from 3202 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 640

Moving on to step 7:
640 goes into 26 0 times with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 12450.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 640

Advancing to step 8:
If we divide 264 by 640, we get 0 and a remainder of 264.
The next digit of our result is 0. 
Result so far: 124500.0
If we take 0 away from 264, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 9:
If we divide 2640 by 640, we get 4 and a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 124500.4
If we subtract 2560 from 2640, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
If we divide 800 by 640, we get 1 and a remainder of 160.
Put 1 as the next digit of the answer. 
Result so far: 124500.41
Subtract 640 from 800 to 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.

Moving on to step 11:
640 can be fit into 1600 2 times, resulting in a remainder of 320.
The next digit of our result is 2. 
Result so far: 124500.412
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.

On to step 12:
3200 divided by 640 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 124500.4125
Subtracting 3200 from 3200 leaves us 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 13:
640 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 124500.4125
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.

Moving on to step 14:
640 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 124500.4125
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.

Our division results in 124500.4125 with a remaining 0.0.
