185871 ÷ 66 
We want to figure out the number of times 185871 can be divided by 66.

Advancing to step 1:
66 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 66

Step 2:
The number 66 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 66

Advancing to step 3:
66 goes into 185 2 times with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 132 from 185 and we're left with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 66

Advancing to step 4:
When dividing 538 by 66, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 528 from 538, we get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 66

Step 5:
107 divided by 66 is 1 with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 281.0
The remainder is 41 after subtracting 66 from 107.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 66

Let's proceed to step 6:
When dividing 411 by 66, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 2816.0
If we subtract 396 from 411, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
66 can be fit into 150 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2816.2
Subtract 132 from 150 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.

Let's proceed to step 8:
180 divided by 66 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 2816.22
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.

The final result is 2816.22 with a remainder of 0.048.
