We're dividing 171912 by 66 
Our goal is to divide 171912 by 66.

Moving on to step 1:
1 divided by 66 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 66

On to step 2:
If we divide 17 by 66, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 66

Step 3:
66 goes into 171 2 times with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 132 away from 171, we end up with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 66

Advancing to step 4:
66 goes into 399 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 396 from 399 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 66

Step 5:
When dividing 31 by 66, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 260.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 66

Let's proceed to step 6:
66 can be fit into 312 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 2604.0
Subtracting 264 from 312 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
480 divided by 66 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 2604.7
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 66, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 2604.72
Subtract 132 from 180 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 66, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 2604.727
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
If we divide 180 by 66, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 2604.7272
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
66 can be fit into 480 7 times, resulting in a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 2604.72727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
When dividing 180 by 66, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 2604.727272
If we subtract 132 from 180, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
The number 66 fits into 480 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 2604.7272727
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
The number 66 fits into 180 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2604.72727272
If we subtract 132 from 180, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 2604.72727272 and a remainder of 4.8e-08.
