We look at the division of 255438 by 39 
We're looking to find how many times 39 goes into 255438.

Advancing to step 1:
39 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 39

Moving on to step 2:
When dividing 25 by 39, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 39

Moving on to step 3:
The number 39 fits into 255 6 times, leaving a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 234 from 255 leaves us with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 39

Going ahead to step 4:
When dividing 214 by 39, we get 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtract 195 from 214 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 39

Moving on to step 5:
39 goes into 193 4 times with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 654.0
If we subtract 156 from 193, we get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 39

Advancing to step 6:
378 divided by 39 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 6549.0
If we take 351 away from 378, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6549.6
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
If we divide 360 by 39, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 6549.69
Deduct 351 from 360 and we're left 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.

Going ahead to step 9:
39 goes into 90 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 6549.692
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 39, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 6549.6923
The remainder is 3 after subtracting 117 from 120.
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 11:
When dividing 30 by 39, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 6549.6923
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
If we divide 300 by 39, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 6549.692307
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
270 divided by 39 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 6549.6923076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
39 goes into 360 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 6549.69230769
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 6549.69230769 with a remaining 9e-09.
