We divide 450297 by 90
Our goal is to divide 450297 by 90.

Let's proceed to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 90

Advancing to step 2:
The number 90 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 90

Let's proceed to step 3:
90 goes into 450 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 0 after subtracting 450 from 450.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 90

Step 4:
When dividing 2 by 90, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 90

Step 5:
90 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 500.0
The remainder is 29 after subtracting 0 from 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 90

Going ahead to step 6:
297 divided by 90 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 5003.0
The remainder is 27 after subtracting 270 from 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
90 goes into 270 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 5003.3
Deduct 270 from 270 and we're left 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.

Let's proceed to step 8:
0 divided by 90 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5003.3
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.

On to step 9:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5003.3
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.

After the division, we end up with 5003.3 and a remainder of 0.0.
