We look at the division of 549239 by 90 
Our goal is to divide 549239 by 90.

Going ahead to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 90

Going ahead to step 2:
90 can be fit into 54 0 times, resulting in a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 90

Advancing to step 3:
The number 90 fits into 549 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 540 from 549 leaves us with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 90

Moving on to step 4:
90 goes into 92 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
The remainder is 2 after subtracting 90 from 92.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 90

Advancing to step 5:
If we divide 23 by 90, we get 0 and a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 610.0
If we take 0 away from 23, we end up with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 90

Let's proceed to step 6:
90 can be fit into 239 2 times, resulting in a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 6102.0
If we subtract 180 from 239, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
90 goes into 590 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 6102.6
Deduct 540 from 590 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.

Going ahead to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 6102.65
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.

On to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 6102.655
If we subtract 450 from 500, 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.

Our division results in 6102.655 with a remaining 0.005.
