688401 divided by 27 
We want to divide 688401 by 27.

Advancing to step 1:
6 divided by 27 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 27

Let's proceed to step 2:
When dividing 68 by 27, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 54 from 68, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 27

Moving on to step 3:
148 divided by 27 is 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 135 from 148 to get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 27

Let's proceed to step 4:
If we divide 134 by 27, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtract 108 from 134 to get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 27

On to step 5:
The number 27 fits into 260 9 times, leaving a remainder of 17.
The next digit of our result is 9. 
Result so far: 2549.0
Deduct 243 from 260 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 27

Let's proceed to step 6:
171 divided by 27 is 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 25496.0
The remainder is 9 after subtracting 162 from 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 27, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 25496.3
Subtracting 81 from 90 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
When dividing 90 by 27, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 25496.33
The remainder is 9 after subtracting 81 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 25496.33 and a remainder of 0.009.
