We divide 639093 by 27
We want to figure out the number of times 639093 can be divided by 27.

Advancing to step 1:
When dividing 6 by 27, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 27

Advancing to step 2:
When dividing 63 by 27, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 54 from 63 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 27

Let's proceed to step 3:
27 can be fit into 99 3 times, resulting in a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 81 from 99 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 27

Let's proceed to step 4:
27 goes into 180 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 236.0
Subtracting 162 from 180 leaves us with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 27

Going ahead to step 5:
If we divide 189 by 27, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 2367.0
If we subtract 189 from 189, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 27

Let's proceed to step 6:
If we divide 3 by 27, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 23670.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
27 goes into 30 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 23670.1
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
If we divide 30 by 27, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 23670.11
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 23670.11 with a remainder of 0.003.
