Let's divide 439389 by 9
We want to figure out the number of times 439389 can be divided by 9.

On to step 1:
9 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

Let's proceed to step 2:
9 goes into 43 4 times with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 36 from 43, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 9

Going ahead to step 3:
9 can be fit into 79 8 times, resulting in a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtract 72 from 79 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 9

On to step 4:
9 can be fit into 73 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 488.0
Deduct 72 from 73 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 9

Step 5:
When dividing 18 by 9, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4882.0
Deduct 18 from 18 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 9

Advancing to step 6:
The number 9 fits into 9 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 48821.0
If we subtract 9 from 9, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 9, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48821.0
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.

Advancing to step 8:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 48821.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 48821.0 with a balance of 0.0.
