We divide 258710 by 31
We want to figure out the number of times 258710 can be divided by 31.

Let's proceed to step 1:
When dividing 2 by 31, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 31

Going ahead to step 2:
When dividing 25 by 31, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 31

Let's proceed to step 3:
31 goes into 258 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 248 from 258, we get 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 31

Moving on to step 4:
When dividing 107 by 31, we get 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 93 from 107 leaves us with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 31

On to step 5:
141 divided by 31 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 834.0
The remainder is 17 after subtracting 124 from 141.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 31

Advancing to step 6:
170 divided by 31 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8345.0
Subtract 155 from 170 to 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.

Going ahead to step 7:
When dividing 150 by 31, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 8345.4
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8345.48
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 8345.483
Deduct 93 from 120 and we're left 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.

Advancing to step 10:
If we divide 270 by 31, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 8345.4838
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 11:
If we divide 220 by 31, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 8345.48387
Subtract 217 from 220 to 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.

Step 12:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 8345.48387
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.

Let's proceed to step 13:
31 goes into 300 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 8345.4838709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
31 can be fit into 210 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 8345.48387096
Subtracting 186 from 210 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 8345.48387096 with a remaining 2.4e-08.
