450874 divided by 40 
We want to figure out the number of times 450874 can be divided by 40.

Let's proceed to step 1:
40 can be fit into 4 0 times, resulting in 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.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 40

Going ahead to step 2:
When dividing 45 by 40, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 40 from 45, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 40

Step 3:
40 goes into 50 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 40 from 50 and we're left with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 40

Let's proceed to step 4:
40 goes into 108 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 112.0
Subtracting 80 from 108 leaves us with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 40

Going ahead to step 5:
The number 40 fits into 287 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 1127.0
Deduct 280 from 287 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 40

On to step 6:
40 can be fit into 74 1 times, resulting in a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 11271.0
Deduct 40 from 74 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
If we divide 340 by 40, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 11271.8
Deduct 320 from 340 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.

Let's proceed to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11271.85
Subtracting 200 from 200 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.

On to step 9:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11271.85
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.

Step 10:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11271.85
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 final result is 11271.85 with a remainder of 0.0.
