We're dividing 448500 by 9 
Our goal is to divide 448500 by 9.

Advancing to step 1:
The number 9 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 9

On to step 2:
If we divide 44 by 9, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 36 from 44 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 9

Going ahead to step 3:
9 can be fit into 88 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 81 from 88 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 9

Let's proceed to step 4:
9 goes into 75 8 times with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 498.0
If we take 72 away from 75, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 9

Step 5:
When dividing 30 by 9, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 4983.0
Subtract 27 from 30 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Let's proceed to step 6:
If we divide 30 by 9, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 49833.0
Subtracting 27 from 30 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 49833.3
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.

Step 8:
9 goes into 30 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 49833.33
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 49833.33, with a leftover of 0.003.
