339717 divided by 1 
Our goal is to divide 339717 by 1.

On to step 1:
If we divide 3 by 1, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Going ahead 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: 33.0
If we subtract 3 from 3, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Going ahead to step 3:
1 goes into 9 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 339.0
The remainder is 0 after subtracting 9 from 9.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Step 4:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 3397.0
Subtracting 7 from 7 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Moving on to step 5:
1 divided by 1 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 33971.0
Deduct 1 from 1 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Going ahead to step 6:
If we divide 7 by 1, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 339717.0
If we take 7 away from 7, we end up 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.
The number 0 becomes the next digit in our result. 
Result so far: 339717.0
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.

Moving on to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 339717.0
If we take 0 away from 0, we end up 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 339717.0, with a leftover of 0.0.
