Let's divide 390068 by 3
Let's see how many times 3 fits into 390068.

Moving on to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

Advancing to step 2:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

Going ahead to step 3:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 130.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Let's proceed to step 4:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1300.0
If we subtract 0 from 0, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

On to step 5:
3 can be fit into 6 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 13002.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Let's proceed to step 6:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 130022.0
Deduct 6 from 8 and we're left 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:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 130022.6
If we take 18 away from 20, we end up 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.

Moving on to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 130022.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 130022.66, with a leftover of 0.002.
