On to step 4:
330 goes into 1239 3 times with a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 990 away from 1239, we end up with 249.
Grab the next digit (0) from the dividend, add it to 249, then carry on: 2490 / 330

Going ahead to step 5:
When dividing 2490 by 330, we get 7 with a remainder of 180.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Subtracting 2310 from 2490 leaves us with 180.
Fetch the next digit (4) from the dividend, attach it to 180 and continue: 1804 / 330

On to step 6:
330 goes into 1804 5 times with a remainder of 154.
Write down 5 as next digit of the result. 
Result so far: 1375.0
Deduct 1650 from 1804 and we're left with 154.
Append the next digit (3) from the dividend to 154 and continue with: 1543 / 330

Advancing to step 7:
The number 330 fits into 1543 4 times, leaving a remainder of 223.
The next digit of our result is 4. 
Result so far: 13754.0
Subtracting 1320 from 1543 leaves us with 223.
Grab the next digit (9) from the dividend, add it to 223, then carry on: 2239 / 330

Advancing to step 8:
2239 divided by 330 is 6 with a remainder of 259.
Record the quotient 6 as the next digit in the result. 
Result so far: 137546.0
Subtracting 1980 from 2239 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 9:
2590 divided by 330 is 7 with a remainder of 280.
Record the quotient 7 as the next digit in the result. 
Result so far: 137546.7
If we take 2310 away from 2590, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
If we divide 2800 by 330, we get 8 and a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 137546.78
If we subtract 2640 from 2800, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
330 goes into 1600 4 times with a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 137546.784
The remainder is 280 after subtracting 1320 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
The number 330 fits into 2800 8 times, leaving a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 137546.7848
The remainder is 160 after subtracting 2640 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
1600 divided by 330 is 4 with a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 137546.78484
Subtracting 1320 from 1600 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 14:
330 goes into 2800 8 times with a remainder of 160.
The next digit of our result is 8. 
Result so far: 137546.784848
Deduct 2640 from 2800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
330 goes into 1600 4 times with a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 137546.7848484
The remainder is 280 after subtracting 1320 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
If we divide 2800 by 330, we get 8 and a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 137546.78484848
The remainder is 160 after subtracting 2640 from 2800.
