We look at the division of 548310 by 90 
Let's see how many times 90 fits into 548310.

Step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 90

Let's proceed to step 2:
54 divided by 90 is 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 90

Let's proceed to step 3:
The number 90 fits into 548 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 540 away from 548, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 90

On to step 4:
90 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (1) from the dividend after 83, then repeat: 831 / 90

On to step 5:
When dividing 831 by 90, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 609.0
The remainder is 21 after subtracting 810 from 831.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 90

Moving on to step 6:
210 divided by 90 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 6092.0
If we take 180 away from 210, we end up 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.

Moving on to step 7:
90 goes into 300 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 6092.3
The remainder is 30 after subtracting 270 from 300.
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.
Record the quotient 3 as the next digit in the result. 
Result so far: 6092.33
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 6092.33 with a remaining 0.03.
