16869 ÷ 27 
We want to figure out the number of times 16869 can be divided by 27.

Let's proceed to step 1:
When dividing 1 by 27, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 27

Going ahead to step 2:
16 divided by 27 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 27

Moving on to step 3:
27 can be fit into 168 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 162 from 168, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 27

Let's proceed to step 4:
The number 27 fits into 66 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we subtract 54 from 66, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 27

Step 5:
If we divide 129 by 27, we get 4 and a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 624.0
The remainder is 21 after subtracting 108 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 6:
When dividing 210 by 27, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 624.7
Subtract 189 from 210 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.

Step 7:
27 goes into 210 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 624.77
If we subtract 189 from 210, we 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.

After the division, we end up with 624.77 and a remainder of 0.021.
