We look at the division of 904378 by 6 
We're looking to find how many times 6 goes into 904378.

Going ahead to step 1:
6 can be fit into 9 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 6 from 9 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 6

On to step 2:
30 divided by 6 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 30 from 30 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 6

Going ahead to step 3:
When dividing 4 by 6, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 6

On to step 4:
When dividing 43 by 6, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 1507.0
If we subtract 42 from 43, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 6

Moving on to step 5:
6 can be fit into 17 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 15072.0
Deduct 12 from 17 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 6

Going ahead to step 6:
58 divided by 6 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 150729.0
The remainder is 4 after subtracting 54 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
6 goes into 40 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 150729.6
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 150729.66
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 150729.66, with a leftover of 0.004.
