If we subtract 0 from 3, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 30

Step 2:
If we divide 33 by 30, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 30 from 33 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 30

Moving on to step 3:
If we divide 38 by 30, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 30 from 38 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 30

Going ahead to step 4:
When dividing 87 by 30, we get 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 112.0
Subtracting 60 from 87 leaves us with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 30

Going ahead to step 5:
The number 30 fits into 270 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1129.0
Subtracting 270 from 270 leaves us 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.

Moving on to step 6:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1129.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1129.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1129.0 with a remaining 0.0.
