9930143 ÷ 30 
We're looking to find how many times 30 goes into 9930143.

Moving on to step 1:
The number 30 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 30

Moving on to step 2:
30 goes into 99 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 90 from 99 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 30

Going ahead to step 3:
When dividing 93 by 30, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 90 from 93 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 30

Advancing to step 4:
The number 30 fits into 30 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 331.0
The remainder is 0 after subtracting 30 from 30.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 30

On to step 5:
If we divide 1 by 30, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 3310.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 30

Let's proceed to step 6:
30 goes into 14 0 times with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 33100.0
Subtract 0 from 14 to get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 30

Moving on to step 7:
The number 30 fits into 143 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 331004.0
Subtracting 120 from 143 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
If we divide 230 by 30, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 331004.7
If we subtract 210 from 230, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 331004.76
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 331004.766
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 331004.766, and the remainder is 0.002.
