339678 ÷ 6 
Let's see how many times 6 fits into 339678.

Going ahead to step 1:
3 divided by 6 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 6

Step 2:
When dividing 33 by 6, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 30 from 33 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 6

Step 3:
39 divided by 6 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 6

Advancing to step 4:
If we divide 36 by 6, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 566.0
Subtract 36 from 36 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 6

Advancing to step 5:
When dividing 7 by 6, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 5661.0
Subtracting 6 from 7 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 6

Advancing to step 6:
If we divide 18 by 6, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 56613.0
Subtracting 18 from 18 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.

Advancing to step 7:
0 divided by 6 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 56613.0
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.

Let's proceed to step 8:
0 divided by 6 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 56613.0
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 56613.0, with a leftover of 0.0.
