Let's divide 138447 by 9
We want to figure out the number of times 138447 can be divided by 9.

Step 1:
If we divide 1 by 9, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 9

Moving on to step 2:
The number 9 fits into 13 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 9 from 13, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 9

Step 3:
48 divided by 9 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 45 from 48 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 9

Going ahead to step 4:
If we divide 34 by 9, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 153.0
Deduct 27 from 34 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 9

Advancing to step 5:
74 divided by 9 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 1538.0
Deduct 72 from 74 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 9

On to step 6:
9 can be fit into 27 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 15383.0
If we take 27 away from 27, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
9 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15383.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 9, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15383.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 15383.0, and the remainder is 0.0.
