We look at the division of 255810 by 31 
We're looking to find how many times 31 goes into 255810.

On to step 1:
If we divide 2 by 31, we get 0 and 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.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 31

Advancing to step 2:
25 divided by 31 is 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.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 31

Step 3:
The number 31 fits into 255 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 248 from 255 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 31

Let's proceed to step 4:
When dividing 78 by 31, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 62 from 78, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 31

On to step 5:
When dividing 161 by 31, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 825.0
Subtracting 155 from 161 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 31

Advancing to step 6:
If we divide 60 by 31, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 8251.0
The remainder is 29 after subtracting 31 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
When dividing 290 by 31, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 8251.9
Subtracting 279 from 290 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
31 goes into 110 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8251.93
Deduct 93 from 110 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
31 goes into 170 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8251.935
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
150 divided by 31 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 8251.9354
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
31 can be fit into 260 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8251.93548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
31 goes into 120 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 8251.935483
Subtracting 93 from 120 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.

Going ahead to step 13:
If we divide 270 by 31, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 8251.9354838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
When dividing 220 by 31, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 8251.93548387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 8251.93548387 and a remainder of 3e-09.
