We're dividing 640792 by 1 
Our goal is to divide 640792 by 1.

Step 1:
1 goes into 6 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Going ahead to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Advancing to step 3:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 640.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Moving on to step 4:
1 goes into 7 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 6407.0
If we subtract 7 from 7, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Moving on to step 5:
1 goes into 9 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 64079.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Going ahead to step 6:
2 divided by 1 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 640792.0
If we subtract 2 from 2, 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.

Moving on to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 640792.0
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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 640792.0
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.

In conclusion, the division gives 640792.0 with a balance of 0.0.
