We divide 455312 by 90
Let's see how many times 90 fits into 455312.

Advancing to 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
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 90

Advancing to step 2:
90 can be fit into 45 0 times, resulting in 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.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 90

Moving on to step 3:
If we divide 455 by 90, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 450 from 455, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 90

Step 4:
When dividing 53 by 90, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 53 to get 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 90

On to step 5:
90 goes into 531 5 times with a remainder of 81.
Write down 5 as next digit of the result. 
Result so far: 505.0
If we take 450 away from 531, we end up with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 90

Let's proceed to step 6:
90 can be fit into 812 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 5059.0
If we take 810 away from 812, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
90 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5059.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5059.02
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
90 goes into 200 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 5059.022
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 5059.022 with a remainder of 0.002.
