We divide 642579 by 27
Let's see how many times 27 fits into 642579.

Moving on to step 1:
6 divided by 27 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 27

On to step 2:
The number 27 fits into 64 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 10 after subtracting 54 from 64.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 27

Going ahead to step 3:
27 goes into 102 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 81 from 102, we get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 27

Let's proceed to step 4:
If we divide 215 by 27, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 237.0
The remainder is 26 after subtracting 189 from 215.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 27

On to step 5:
267 divided by 27 is 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 2379.0
If we take 243 away from 267, we end up with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 27

Let's proceed to step 6:
249 divided by 27 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 23799.0
Deduct 243 from 249 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 27, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 23799.2
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 27 fits into 60 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 23799.22
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 23799.22 with a remainder of 0.006.
