378303 divided by 9 
Our goal is to divide 378303 by 9.

Let's proceed to step 1:
9 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 9

Moving on to step 2:
When dividing 37 by 9, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 36 from 37 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 9

Going ahead to step 3:
The number 9 fits into 18 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 18 from 18 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 9

Step 4:
3 divided by 9 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 9

Let's proceed to step 5:
30 divided by 9 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 4203.0
If we subtract 27 from 30, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 9

On to step 6:
9 goes into 33 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 42033.0
Subtracting 27 from 33 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 9 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 42033.6
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
The number 9 fits into 60 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 42033.66
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 42033.66 with a balance of 0.006.
