We divide 257859 by 31
Let's see how many times 31 fits into 257859.

Moving on to step 1:
2 divided by 31 is 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.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 31

Advancing to step 2:
31 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 31

On to step 3:
31 can be fit into 257 8 times, resulting in a remainder of 9.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 248 from 257 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 31

On to step 4:
31 goes into 98 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 83.0
If we subtract 93 from 98, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 31

Step 5:
If we divide 55 by 31, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 831.0
If we take 31 away from 55, we end up with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 31

Let's proceed to step 6:
249 divided by 31 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8318.0
Deduct 248 from 249 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 31, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8318.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 31, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 8318.03
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
The number 31 fits into 70 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8318.032
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
If we divide 80 by 31, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 8318.0322
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 8318.0322, with a leftover of 0.00018.
