We divide 452028 by 90
We're looking to find how many times 90 goes into 452028.

Step 1:
90 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 90

Going ahead to step 2:
When dividing 45 by 90, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 90

Let's proceed to step 3:
If we divide 452 by 90, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 450 from 452, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 90

Let's proceed to step 4:
The number 90 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtract 0 from 20 to get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 90

Moving on to step 5:
When dividing 202 by 90, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 502.0
Deduct 180 from 202 and we're left with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 90

On to step 6:
If we divide 228 by 90, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 5022.0
Subtracting 180 from 228 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
If we divide 480 by 90, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5022.5
If we subtract 450 from 480, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 5022.53
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
The number 90 fits into 300 3 times, leaving a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 5022.533
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 5022.533 with a remaining 0.003.
