On to step 1:
The number 660 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 660

Step 2:
660 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 660

Advancing to step 3:
762 divided by 660 is 1 with a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 660 away from 762, we end up with 102.

Moving on to step 4:
1025 divided by 660 is 1 with a remainder of 365.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 660 from 1025 leaves us with 365.
Include the next digit (5) from the dividend after 365, then repeat: 3655 / 660

On to step 5:
The number 660 fits into 3655 5 times, leaving a remainder of 355.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtract 3300 from 3655 to get 355.
Append the next digit (8) from the dividend to 355 and continue with: 3558 / 660

On to step 6:
3558 divided by 660 is 5 with a remainder of 258.
The next digit of our result is 5. 
Result so far: 1155.0
Subtracting 3300 from 3558 leaves us with 258.
Append the next digit (7) from the dividend to 258 and continue with: 2587 / 660

Let's proceed to step 7:
2587 divided by 660 is 3 with a remainder of 607.
The next digit of our result is 3. 
Result so far: 11553.0
If we take 1980 away from 2587, we end up with 607.
Grab the next digit (1) from the dividend, add it to 607, then carry on: 6071 / 660

Advancing to step 8:
The number 660 fits into 6071 9 times, leaving a remainder of 131.
Record the quotient 9 as the next digit in the result. 
Result so far: 115539.0
The remainder is 131 after subtracting 5940 from 6071.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 9:
660 goes into 1310 1 times with a remainder of 650.
Use 1 as the next digit of our solution. 
Result so far: 115539.1
Subtracting 660 from 1310 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 10:
6500 divided by 660 is 9 with a remainder of 560.
Write down 9 as next digit of the result. 
Result so far: 115539.19
If we take 5940 away from 6500, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 11:
660 can be fit into 5600 8 times, resulting in a remainder of 320.
The next digit of our result is 8. 
Result so far: 115539.198
Subtracting 5280 from 5600 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
The number 660 fits into 3200 4 times, leaving a remainder of 560.
Use 4 as the next digit of our solution. 
Result so far: 115539.1984
If we subtract 2640 from 3200, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 13:
660 goes into 5600 8 times with a remainder of 320.
The number 8 becomes the next digit in our result. 
Result so far: 115539.19848
Deduct 5280 from 5600 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
660 can be fit into 3200 4 times, resulting in a remainder of 560.
Put 4 as the next digit of the answer. 
Result so far: 115539.198484
Deduct 2640 from 3200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
5600 divided by 660 is 8 with a remainder of 320.
The next digit of our result is 8. 
Result so far: 115539.1984848
Deduct 5280 from 5600 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 16:
660 goes into 3200 4 times with a remainder of 560.
Put 4 as the next digit of the answer. 
Result so far: 115539.19848484
If we take 2640 away from 3200, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 115539.19848484 with a remainder of 5.6e-07.
