We're dividing 390648 by 6 
Let's see how many times 6 fits into 390648.

On to step 1:
The number 6 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 6

Let's proceed to step 2:
6 goes into 39 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 6

Let's proceed to step 3:
6 can be fit into 30 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtract 30 from 30 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 6

Let's proceed to step 4:
6 can be fit into 6 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 651.0
Deduct 6 from 6 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 6

Moving on to step 5:
The number 6 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 6510.0
If we take 0 away from 4, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 6

Moving on to step 6:
48 divided by 6 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 65108.0
If we take 48 away from 48, 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 6 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 65108.0
Subtract 0 from 0 to 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 8:
When dividing 0 by 6, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 65108.0
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.

After the division, we end up with 65108.0 and a remainder of 0.0.
