We're dividing 291143 by 30 
We want to figure out the number of times 291143 can be divided by 30.

Advancing to step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 30

Going ahead to step 2:
If we divide 29 by 30, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 30

Advancing to step 3:
30 goes into 291 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 270 from 291 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 30

Going ahead to step 4:
If we divide 211 by 30, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we take 210 away from 211, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 30

Let's proceed to step 5:
14 divided by 30 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 970.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 30

Step 6:
30 can be fit into 143 4 times, resulting in a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 9704.0
Deduct 120 from 143 and we're left 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.

Step 7:
230 divided by 30 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 9704.7
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.

Advancing to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 9704.76
Subtracting 180 from 200 leaves us 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.

Advancing to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 9704.766
Subtracting 180 from 200 leaves us 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.

Our division results in 9704.766 with a remaining 0.002.
