We're dividing 171885 by 66 
We want to figure out the number of times 171885 can be divided by 66.

Step 1:
66 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 66

Moving on to step 2:
The number 66 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 66

Moving on to step 3:
66 goes into 171 2 times with a remainder of 39.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 132 from 171 and we're left with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 66

Step 4:
When dividing 398 by 66, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 26.0
If we take 396 away from 398, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 66

Moving on to step 5:
66 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 260.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 66

Advancing to step 6:
66 can be fit into 285 4 times, resulting in a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 2604.0
Subtract 264 from 285 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
66 can be fit into 210 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 2604.3
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
If we divide 120 by 66, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 2604.31
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
540 divided by 66 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2604.318
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
66 goes into 120 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 2604.3181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
66 goes into 540 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 2604.31818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 2604.318181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
If we divide 540 by 66, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 2604.3181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
120 divided by 66 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 2604.31818181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 2604.31818181 with a remainder of 5.4e-08.
