39378 divided by 9 
We're looking to find how many times 9 goes into 39378.

Advancing to step 1:
9 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 9

Advancing to step 2:
When dividing 39 by 9, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 3 after subtracting 36 from 39.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 9

On to step 3:
9 goes into 33 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 27 from 33 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 9

Let's proceed to step 4:
The number 9 fits into 67 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 437.0
Deduct 63 from 67 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 9

Moving on to step 5:
The number 9 fits into 48 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 4375.0
If we subtract 45 from 48, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
30 divided by 9 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 4375.3
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 9 fits into 30 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 4375.33
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 4375.33 with a remaining 0.003.
