We're dividing 639279 by 1 
Let's see how many times 1 fits into 639279.

Moving on to step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Moving on to step 2:
3 divided by 1 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 3 from 3, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 3:
9 divided by 1 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 639.0
The remainder is 0 after subtracting 9 from 9.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Step 4:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 6392.0
Subtracting 2 from 2 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Step 5:
1 goes into 7 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 63927.0
Subtract 7 from 7 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Let's proceed to step 6:
1 goes into 9 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 639279.0
Subtracting 9 from 9 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.

On to step 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 639279.0
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.

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 639279.0
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.

The final outcome is 639279.0, with a leftover of 0.0.
