When dividing 666 by 171, we get 3 with a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 173.0
Subtracting 513 from 666 leaves us with 153.
Fetch the next digit (9) from the dividend, attach it to 153 and continue: 1539 / 171

On to step 6:
171 goes into 1539 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1739.0
The remainder is 0 after subtracting 1539 from 1539.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 171

Advancing to step 7:
171 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 17390.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 171

On to step 8:
171 goes into 71 0 times with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 173900.0
If we take 0 away from 71, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
171 can be fit into 710 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 173900.4
Subtract 684 from 710 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 171, we get 1 with a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 173900.41
Subtracting 171 from 260 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 11:
890 divided by 171 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 173900.415
Deduct 855 from 890 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 171 fits into 350 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 173900.4152
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
171 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 173900.4152
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
171 can be fit into 800 4 times, resulting in a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 173900.415204
The remainder is 116 after subtracting 684 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 15:
The number 171 fits into 1160 6 times, leaving a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 173900.4152046
Deduct 1026 from 1160 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 16:
171 can be fit into 1340 7 times, resulting in a remainder of 143.
The next digit of our result is 7. 
Result so far: 173900.41520467
The remainder is 143 after subtracting 1197 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final result is 173900.41520467 with a remainder of 1.43e-07.
