Let's divide 508998 by 90
We're looking to find how many times 90 goes into 508998.

Step 1:
90 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 90

Let's proceed to step 2:
If we divide 50 by 90, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 90

On to step 3:
When dividing 508 by 90, we get 5 with a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 450 from 508 to get 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 90

Let's proceed to step 4:
90 goes into 589 6 times with a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we take 540 away from 589, we end up with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 90

Going ahead to step 5:
The number 90 fits into 499 5 times, leaving a remainder of 49.
The next digit of our result is 5. 
Result so far: 565.0
If we take 450 away from 499, we end up with 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 90

Let's proceed to step 6:
90 can be fit into 498 5 times, resulting in a remainder of 48.
The next digit of our result is 5. 
Result so far: 5655.0
If we take 450 away from 498, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
When dividing 480 by 90, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 5655.5
Deduct 450 from 480 and we're left 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.

Going ahead to step 8:
90 goes into 300 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 5655.53
If we take 270 away from 300, 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.

Going ahead to step 9:
If we divide 300 by 90, we get 3 and a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 5655.533
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 5655.533 with a remaining 0.003.
