We look at the division of 251349 by 31 
We want to divide 251349 by 31.

Step 1:
When dividing 2 by 31, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 31

Step 2:
When dividing 25 by 31, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 31

Let's proceed to step 3:
The number 31 fits into 251 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 248 away from 251, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 31

Step 4:
If we divide 33 by 31, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we subtract 31 from 33, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 31

Advancing to step 5:
24 divided by 31 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 810.0
If we subtract 0 from 24, we get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 31

Going ahead to step 6:
249 divided by 31 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8108.0
If we subtract 248 from 249, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 31, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8108.0
If we subtract 0 from 10, we get 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:
100 divided by 31 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8108.03
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
If we divide 70 by 31, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8108.032
If we take 62 away from 70, we end up with 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:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 8108.0322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 8108.0322 and a remainder of 0.00018.
