Let's divide 450153 by 45
Let's see how many times 45 fits into 450153.

Going ahead to step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 45

Moving on to step 2:
45 divided by 45 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 45 from 45 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 45

Let's proceed to step 3:
0 divided by 45 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 45

Step 4:
When dividing 1 by 45, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 45

Moving on to step 5:
When dividing 15 by 45, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 1000.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 45

Going ahead to step 6:
When dividing 153 by 45, we get 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 10003.0
Subtracting 135 from 153 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
180 divided by 45 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 10003.4
Subtracting 180 from 180 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.

Going ahead to step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10003.4
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.

Moving on to step 9:
If we divide 0 by 45, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 10003.4
Subtract 0 from 0 to 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.

The final outcome is 10003.4, with a leftover of 0.0.
