We look at the division of 45916403 by 450 
We want to figure out the number of times 45916403 can be divided by 450.

Advancing to step 1:
When dividing 4 by 450, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 450

Let's proceed to step 2:
45 divided by 450 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 450

Advancing to step 3:
459 divided by 450 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 450 away from 459, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 450

Let's proceed to step 4:
450 goes into 91 0 times with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 91 to get 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 450

Step 5:
If we divide 916 by 450, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 102.0
Deduct 900 from 916 and we're left with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 450

Step 6:
If we divide 164 by 450, we get 0 and a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
Subtract 0 from 164 to get 164.
Take the next digit (0) from the dividend and append it to 164, then repeat: 1640 / 450

On to step 7:
If we divide 1640 by 450, we get 3 and a remainder of 290.
The number 3 becomes the next digit in our result. 
Result so far: 10203.0
If we subtract 1350 from 1640, we get 290.
Take the next digit (3) from the dividend and append it to 290, then repeat: 2903 / 450

Going ahead to step 8:
If we divide 2903 by 450, we get 6 and a remainder of 203.
Use 6 as the next digit of our solution. 
Result so far: 102036.0
Subtracting 2700 from 2903 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 9:
450 goes into 2030 4 times with a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 102036.4
Deduct 1800 from 2030 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
The number 450 fits into 2300 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 102036.45
Subtract 2250 from 2300 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
450 can be fit into 500 1 times, resulting in a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 102036.451
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
The number 450 fits into 500 1 times, leaving a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 102036.4511
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 102036.4511, with a leftover of 0.0005.
