We're dividing 16686 by 66 
Our goal is to divide 16686 by 66.

Going ahead to 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 (6) from the dividend after 1, then repeat: 16 / 66

Let's proceed to step 2:
16 divided by 66 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 66

Let's proceed to step 3:
66 can be fit into 166 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 132 from 166, we get 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 66

Advancing to step 4:
348 divided by 66 is 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 18 after subtracting 330 from 348.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 66

Advancing to step 5:
If we divide 186 by 66, we get 2 and a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 252.0
If we take 132 away from 186, 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.

Step 6:
If we divide 540 by 66, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 252.8
Deduct 528 from 540 and we're left 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 7:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 252.81
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 8:
When dividing 540 by 66, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 252.818
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 9:
If we divide 120 by 66, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 252.8181
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.

Going ahead to step 10:
540 divided by 66 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 252.81818
Subtracting 528 from 540 leaves us 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.

Let's proceed to step 11:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 252.818181
Deduct 66 from 120 and we're left 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.

Let's proceed to step 12:
66 goes into 540 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 252.8181818
Deduct 528 from 540 and we're left 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.

Let's proceed to step 13:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 252.81818181
Subtract 66 from 120 to 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.

In conclusion, the division gives 252.81818181 with a balance of 5.4e-08.
