Let's divide 448503 by 40
Let's see how many times 40 fits into 448503.

Step 1:
When dividing 4 by 40, we get 0 with a remainder of 4.
Write down 0 as next digit of the 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 / 40

Going ahead to step 2:
44 divided by 40 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 40 from 44, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 40

On to step 3:
The number 40 fits into 48 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 40 from 48, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 40

Going ahead to step 4:
When dividing 85 by 40, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtracting 80 from 85 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 40

Let's proceed to step 5:
40 can be fit into 50 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1121.0
Subtracting 40 from 50 leaves us with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 40

On to step 6:
When dividing 103 by 40, we get 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 11212.0
Subtracting 80 from 103 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 40 fits into 230 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 11212.5
Deduct 200 from 230 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
40 goes into 300 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 11212.57
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 11212.575
If we subtract 200 from 200, 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.

Let's proceed to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11212.575
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11212.575
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 11212.575 with a balance of 0.0.
