Let's divide 550998 by 90
Let's see how many times 90 fits into 550998.

Moving on to step 1:
90 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 90

Moving on to step 2:
55 divided by 90 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 90

Going ahead to step 3:
90 can be fit into 550 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 540 from 550 and we're left with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 90

Going ahead to step 4:
The number 90 fits into 109 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 61.0
If we subtract 90 from 109, we get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 90

Let's proceed to step 5:
90 goes into 199 2 times with a remainder of 19.
The next digit of our result is 2. 
Result so far: 612.0
The remainder is 19 after subtracting 180 from 199.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 90

Let's proceed to step 6:
90 goes into 198 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 6122.0
If we subtract 180 from 198, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 90 fits into 180 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 6122.2
Deduct 180 from 180 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6122.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 90 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6122.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 6122.2 with a balance of 0.0.
