We look at the division of 990574 by 30 
We want to divide 990574 by 30.

Step 1:
When dividing 9 by 30, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 30

Moving on to step 2:
99 divided by 30 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 90 from 99 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 30

Moving on to step 3:
90 divided by 30 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 90 from 90 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 30

Going ahead to step 4:
30 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 330.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 30

Going ahead to step 5:
57 divided by 30 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 3301.0
The remainder is 27 after subtracting 30 from 57.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 30

Moving on to step 6:
30 goes into 274 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 33019.0
Deduct 270 from 274 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 30 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 33019.1
Subtract 30 from 40 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 33019.13
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 33019.133
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 33019.133, with a leftover of 0.001.
