478547 divided by 90 
Our goal is to divide 478547 by 90.

Step 1:
90 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 90

Moving on to step 2:
90 goes into 47 0 times with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 90

Going ahead to step 3:
90 can be fit into 478 5 times, resulting in a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 28 after subtracting 450 from 478.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 90

Step 4:
If we divide 285 by 90, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Deduct 270 from 285 and we're left with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 90

Let's proceed to step 5:
The number 90 fits into 154 1 times, leaving a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 531.0
Subtract 90 from 154 to get 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 90

Step 6:
90 goes into 647 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 5317.0
If we subtract 630 from 647, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
90 can be fit into 170 1 times, resulting in a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 5317.1
Subtracting 90 from 170 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 5317.18
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
If we divide 800 by 90, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 5317.188
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 5317.188, with a leftover of 0.008.
