We're dividing 451904 by 9 
Let's see how many times 9 fits into 451904.

Let's proceed to step 1:
9 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 9

Step 2:
9 can be fit into 45 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 45 from 45, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 9

On to step 3:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 9

On to step 4:
The number 9 fits into 19 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 502.0
Subtract 18 from 19 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 9

On to step 5:
9 can be fit into 10 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 5021.0
If we take 9 away from 10, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 9

On to step 6:
The number 9 fits into 14 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 50211.0
Subtracting 9 from 14 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 9 fits into 50 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 50211.5
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
50 divided by 9 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 50211.55
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 50211.55 with a balance of 0.005.
