We divide 472721 by 90
We're looking to find how many times 90 goes into 472721.

Step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 90

Going ahead to step 2:
90 goes into 47 0 times with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Take the next digit (2) from the dividend and append it to 47, then repeat: 472 / 90

On to step 3:
472 divided by 90 is 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 450 from 472 and we're left with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 90

Let's proceed to step 4:
When dividing 227 by 90, we get 2 with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 47 after subtracting 180 from 227.
Bring next digit (2) of the dividend behind the 47 and repeat the process: 472 / 90

Step 5:
90 can be fit into 472 5 times, resulting in a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 525.0
The remainder is 22 after subtracting 450 from 472.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 90

Moving on to step 6:
221 divided by 90 is 2 with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 5252.0
The remainder is 41 after subtracting 180 from 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
When dividing 410 by 90, we get 4 with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 5252.4
If we subtract 360 from 410, we 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.

Step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 5252.45
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.

Moving on to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5252.455
Deduct 450 from 500 and we're left 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.

After the division, we end up with 5252.455 and a remainder of 0.005.
