We look at the division of 189851 by 66 
We're looking to find how many times 66 goes into 189851.

Advancing to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 66

Step 2:
66 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 66

Step 3:
If we divide 189 by 66, we get 2 and a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 132 from 189 and we're left with 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 66

On to step 4:
578 divided by 66 is 8 with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 50 after subtracting 528 from 578.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 66

Moving on to step 5:
If we divide 505 by 66, we get 7 and a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Subtract 462 from 505 to get 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 66

Moving on to step 6:
If we divide 431 by 66, we get 6 and a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 2876.0
If we subtract 396 from 431, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
If we divide 350 by 66, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2876.5
Subtracting 330 from 350 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
66 goes into 200 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 2876.53
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
20 divided by 66 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2876.53
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
If we divide 200 by 66, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 2876.5303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
66 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2876.5303
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
The number 66 fits into 200 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 2876.530303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 2876.530303
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
66 goes into 200 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 2876.53030303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 2876.53030303 with a remaining 2e-09.
