255190 divided by 39 
We want to figure out the number of times 255190 can be divided by 39.

Going ahead to step 1:
When dividing 2 by 39, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 39

Advancing to step 2:
If we divide 25 by 39, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 39

On to step 3:
39 goes into 255 6 times with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 234 away from 255, we end up with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 39

Going ahead to step 4:
39 can be fit into 211 5 times, resulting in a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtracting 195 from 211 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 39

Let's proceed to step 5:
169 divided by 39 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 654.0
The remainder is 13 after subtracting 156 from 169.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 39

Moving on to step 6:
If we divide 130 by 39, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 6543.0
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
When dividing 130 by 39, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 6543.3
Subtract 117 from 130 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
If we divide 130 by 39, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 6543.33
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 6543.33 with a remaining 0.013.
