Let's divide 621396 by 27
We're looking to find how many times 27 goes into 621396.

Advancing to step 1:
The number 27 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 27

Moving on to step 2:
When dividing 62 by 27, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 54 from 62, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 27

Advancing to step 3:
If we divide 81 by 27, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 81 away from 81, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 27

Let's proceed to step 4:
3 divided by 27 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 230.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 27

Advancing to step 5:
39 divided by 27 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 2301.0
Subtract 27 from 39 to get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 27

Let's proceed to step 6:
126 divided by 27 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 23014.0
If we take 108 away from 126, 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 7:
The number 27 fits into 180 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 23014.6
Subtracting 162 from 180 leaves us 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.

Let's proceed to step 8:
If we divide 180 by 27, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 23014.66
Subtracting 162 from 180 leaves us 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.

In conclusion, the division gives 23014.66 with a balance of 0.018.
