We're dividing 39138927 by 9 
We want to figure out the number of times 39138927 can be divided by 9.

Moving on to step 1:
When dividing 3 by 9, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 9

Moving on to step 2:
When dividing 39 by 9, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 36 from 39 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 9

Step 3:
31 divided by 9 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 27 from 31 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 9

On to step 4:
9 goes into 43 4 times with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
Deduct 36 from 43 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 9

Going ahead to step 5:
When dividing 78 by 9, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 4348.0
If we subtract 72 from 78, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 9

Step 6:
The number 9 fits into 69 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 43487.0
Subtracting 63 from 69 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 9

Let's proceed to step 7:
The number 9 fits into 62 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 434876.0
The remainder is 8 after subtracting 54 from 62.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 9

Going ahead to step 8:
When dividing 87 by 9, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 4348769.0
Subtract 81 from 87 to 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 9:
60 divided by 9 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 4348769.6
Subtract 54 from 60 to 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.

Going ahead to step 10:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 4348769.66
Deduct 54 from 60 and we're left 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.

The final outcome is 4348769.66, with a leftover of 0.006.
