16866 ÷ 48 
We're looking to find how many times 48 goes into 16866.

Advancing to step 1:
The number 48 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 48

Going ahead to step 2:
16 divided by 48 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.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 48

Let's proceed to step 3:
When dividing 168 by 48, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 144 from 168 and we're left with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 48

Going ahead to step 4:
When dividing 246 by 48, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 240 away from 246, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 48

Let's proceed to step 5:
48 goes into 66 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 351.0
If we take 48 away from 66, we end up 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.

On to step 6:
48 can be fit into 180 3 times, resulting in a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 351.3
Subtracting 144 from 180 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
The number 48 fits into 360 7 times, leaving a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 351.37
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
48 goes into 240 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 351.375
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 351.375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 48, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 351.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 351.375, and the remainder is 0.0.
