We're dividing 668378 by 9 
We want to divide 668378 by 9.

Advancing to step 1:
6 divided by 9 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 9

Advancing to step 2:
9 goes into 66 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 63 from 66, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 9

Going ahead to step 3:
38 divided by 9 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 74.0
Deduct 36 from 38 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 9

Let's proceed to step 4:
9 can be fit into 23 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 742.0
If we take 18 away from 23, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 9

Let's proceed to step 5:
57 divided by 9 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 7426.0
The remainder is 3 after subtracting 54 from 57.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 9

Let's proceed to step 6:
If we divide 38 by 9, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 74264.0
If we subtract 36 from 38, 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.

Going ahead to step 7:
9 can be fit into 20 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 74264.2
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.

On to step 8:
9 goes into 20 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 74264.22
Subtracting 18 from 20 leaves us 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.

In conclusion, the division gives 74264.22 with a balance of 0.002.
