498990 ÷ 30 
We want to figure out the number of times 498990 can be divided by 30.

Let's proceed to step 1:
The number 30 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 30

Advancing to step 2:
When dividing 49 by 30, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 30 from 49 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 30

Step 3:
When dividing 198 by 30, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 18 after subtracting 180 from 198.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 30

On to step 4:
30 goes into 189 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Subtracting 180 from 189 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 30

Going ahead to step 5:
30 can be fit into 99 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 1663.0
If we take 90 away from 99, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 30

Step 6:
When dividing 90 by 30, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 16633.0
If we take 90 away from 90, we end up 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.

Let's proceed to step 7:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16633.0
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.

Step 8:
30 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16633.0
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.

The final result is 16633.0 with a remainder of 0.0.
