330 goes into 790 2 times with a remainder of 130.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 660 from 790 and we're left with 130.
Include the next digit (1) from the dividend after 130, then repeat: 1301 / 330

Advancing to step 4:
330 can be fit into 1301 3 times, resulting in a remainder of 311.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 990 from 1301 and we're left with 311.
Append the next digit (9) from the dividend to 311 and continue with: 3119 / 330

Advancing to step 5:
The number 330 fits into 3119 9 times, leaving a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
The remainder is 149 after subtracting 2970 from 3119.
Fetch the next digit (5) from the dividend, attach it to 149 and continue: 1495 / 330

Advancing to step 6:
The number 330 fits into 1495 4 times, leaving a remainder of 175.
The next digit of our result is 4. 
Result so far: 2394.0
Deduct 1320 from 1495 and we're left with 175.
Take the next digit (5) from the dividend and append it to 175, then repeat: 1755 / 330

Advancing to step 7:
330 goes into 1755 5 times with a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 23945.0
Subtract 1650 from 1755 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 8:
330 goes into 1050 3 times with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 23945.3
If we subtract 990 from 1050, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
The number 330 fits into 600 1 times, leaving a remainder of 270.
The next digit of our result is 1. 
Result so far: 23945.31
Subtracting 330 from 600 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 10:
330 goes into 2700 8 times with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 23945.318
The remainder is 60 after subtracting 2640 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
The number 330 fits into 600 1 times, leaving a remainder of 270.
Write down 1 as next digit of the result. 
Result so far: 23945.3181
Subtracting 330 from 600 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 12:
If we divide 2700 by 330, we get 8 and a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 23945.31818
Deduct 2640 from 2700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
The number 330 fits into 600 1 times, leaving a remainder of 270.
The number 1 becomes the next digit in our result. 
Result so far: 23945.318181
The remainder is 270 after subtracting 330 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 14:
When dividing 2700 by 330, we get 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 23945.3181818
Subtract 2640 from 2700 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
If we divide 600 by 330, we get 1 and a remainder of 270.
Use 1 as the next digit of our solution. 
Result so far: 23945.31818181
The remainder is 270 after subtracting 330 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.
