We look at the division of 248493 by 31 
We want to divide 248493 by 31.

Going ahead to step 1:
If we divide 2 by 31, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 31

Going ahead to step 2:
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: 0.0
Subtract 0 from 24 to get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 31

Advancing to step 3:
When dividing 248 by 31, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 0 after subtracting 248 from 248.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 31

Let's proceed to step 4:
4 divided by 31 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 31

Step 5:
If we divide 49 by 31, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 801.0
Deduct 31 from 49 and we're left with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 31

Let's proceed to step 6:
The number 31 fits into 183 5 times, leaving a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 8015.0
Deduct 155 from 183 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
The number 31 fits into 280 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 8015.9
Deduct 279 from 280 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.

On to step 8:
The number 31 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8015.9
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.

Advancing to step 9:
If we divide 100 by 31, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8015.903
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.

Advancing to step 10:
70 divided by 31 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 8015.9032
Subtract 62 from 70 to 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 11:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 8015.90322
Subtract 62 from 80 to get 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 result is 8015.90322 with a remainder of 1.8e-05.
