We're dividing 51809409 by 330 
Let's see how many times 330 fits into 51809409.

On to step 1:
When dividing 5 by 330, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 330

Advancing to step 2:
330 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 330

Moving on to step 3:
If we divide 518 by 330, we get 1 and a remainder of 188.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 330 from 518 leaves us with 188.
Include the next digit (0) from the dividend after 188, then repeat: 1880 / 330

Step 4:
330 goes into 1880 5 times with a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 1650 from 1880 and we're left with 230.
Fetch the next digit (9) from the dividend, attach it to 230 and continue: 2309 / 330

Step 5:
2309 divided by 330 is 6 with a remainder of 329.
The next digit of our result is 6. 
Result so far: 156.0
The remainder is 329 after subtracting 1980 from 2309.
Take the next digit (4) from the dividend and append it to 329, then repeat: 3294 / 330

Moving on to step 6:
3294 divided by 330 is 9 with a remainder of 324.
Record the quotient 9 as the next digit in the result. 
Result so far: 1569.0
If we take 2970 away from 3294, we end up with 324.
Bring next digit (0) of the dividend behind the 324 and repeat the process: 3240 / 330

Step 7:
330 goes into 3240 9 times with a remainder of 270.
Put 9 as the next digit of the answer. 
Result so far: 15699.0
Deduct 2970 from 3240 and we're left with 270.
Append the next digit (9) from the dividend to 270 and continue with: 2709 / 330

Advancing to step 8:
The number 330 fits into 2709 8 times, leaving a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 156998.0
If we subtract 2640 from 2709, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
The number 330 fits into 690 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 156998.2
Subtract 660 from 690 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 330 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 156998.2
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
330 goes into 3000 9 times with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 156998.209
If we take 2970 away from 3000, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
330 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 156998.209
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 13:
330 can be fit into 3000 9 times, resulting in a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 156998.20909
If we take 2970 away from 3000, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
The number 330 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 156998.20909
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
330 can be fit into 3000 9 times, resulting in a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 156998.2090909
If we subtract 2970 from 3000, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
330 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 156998.2090909
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 156998.2090909 with a remaining 3e-07.
