1003315 divided by 450 
We want to figure out the number of times 1003315 can be divided by 450.

On to step 1:
The number 450 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 450

Let's proceed to step 2:
10 divided by 450 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 450

Advancing to step 3:
When dividing 100 by 450, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 100 and we're left with 100.
Grab the next digit (3) from the dividend, add it to 100, then carry on: 1003 / 450

Going ahead to step 4:
450 goes into 1003 2 times with a remainder of 103.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 900 from 1003 and we're left with 103.
Grab the next digit (3) from the dividend, add it to 103, then carry on: 1033 / 450

On to step 5:
450 goes into 1033 2 times with a remainder of 133.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 900 from 1033, we get 133.
Fetch the next digit (1) from the dividend, attach it to 133 and continue: 1331 / 450

Step 6:
If we divide 1331 by 450, we get 2 and a remainder of 431.
The next digit of our result is 2. 
Result so far: 222.0
Deduct 900 from 1331 and we're left with 431.
Append the next digit (5) from the dividend to 431 and continue with: 4315 / 450

Step 7:
If we divide 4315 by 450, we get 9 and a remainder of 265.
The next digit of our result is 9. 
Result so far: 2229.0
Subtracting 4050 from 4315 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 8:
2650 divided by 450 is 5 with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 2229.5
If we subtract 2250 from 2650, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 9:
The number 450 fits into 4000 8 times, leaving a remainder of 400.
Put 8 as the next digit of the answer. 
Result so far: 2229.58
Subtracting 3600 from 4000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 10:
The number 450 fits into 4000 8 times, leaving a remainder of 400.
The next digit of our result is 8. 
Result so far: 2229.588
Subtracting 3600 from 4000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 2229.588 with a remainder of 0.04.
