Moving on to step 5:
The number 660 fits into 6588 9 times, leaving a remainder of 648.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 5940 from 6588, we get 648.
Include the next digit (8) from the dividend after 648, then repeat: 6488 / 660

Advancing to step 6:
660 goes into 6488 9 times with a remainder of 548.
The number 9 becomes the next digit in our result. 
Result so far: 299.0
The remainder is 548 after subtracting 5940 from 6488.
Take the next digit (1) from the dividend and append it to 548, then repeat: 5481 / 660

Step 7:
5481 divided by 660 is 8 with a remainder of 201.
Put 8 as the next digit of the answer. 
Result so far: 2998.0
Deduct 5280 from 5481 and we're left with 201.
Include the next digit (9) from the dividend after 201, then repeat: 2019 / 660

Advancing to step 8:
660 can be fit into 2019 3 times, resulting in a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 29983.0
If we take 1980 away from 2019, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
660 can be fit into 390 0 times, resulting in a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 29983.0
If we subtract 0 from 390, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
660 can be fit into 3900 5 times, resulting in a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 29983.05
Subtracting 3300 from 3900 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
660 can be fit into 6000 9 times, resulting in a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 29983.059
The remainder is 60 after subtracting 5940 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
When dividing 600 by 660, we get 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 29983.059
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 13:
The number 660 fits into 6000 9 times, leaving a remainder of 60.
The next digit of our result is 9. 
Result so far: 29983.05909
The remainder is 60 after subtracting 5940 from 6000.
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 14:
When dividing 600 by 660, we get 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 29983.05909
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 15:
660 can be fit into 6000 9 times, resulting in a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 29983.0590909
If we take 5940 away from 6000, we end up 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.

Step 16:
660 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 29983.0590909
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 29983.0590909 with a remaining 6e-07.
