640792 ÷ 5 
We want to divide 640792 by 5.

On to step 1:
5 can be fit into 6 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 6 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 5

On to step 2:
When dividing 14 by 5, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 10 from 14 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 5

Moving on to step 3:
5 goes into 40 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 5

On to step 4:
If we divide 7 by 5, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1281.0
Deduct 5 from 7 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 5

On to step 5:
The number 5 fits into 29 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 12815.0
If we take 25 away from 29, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 5

On to step 6:
When dividing 42 by 5, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 128158.0
Subtracting 40 from 42 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 5, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 128158.4
Deduct 20 from 20 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 8:
0 divided by 5 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 128158.4
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.

Let's proceed to step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 128158.4
Subtracting 0 from 0 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.

In conclusion, the division gives 128158.4 with a balance of 0.0.
