Let's divide 813933 by 31
Let's see how many times 31 fits into 813933.

On to step 1:
31 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 31

Going ahead to step 2:
The number 31 fits into 81 2 times, leaving a remainder of 19.
The next digit of our result is 2. 
Result so far: 2.0
If we take 62 away from 81, we end up with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 31

Going ahead to step 3:
When dividing 193 by 31, we get 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 26.0
If we take 186 away from 193, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 31

Going ahead to step 4:
If we divide 79 by 31, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 262.0
Deduct 62 from 79 and we're left with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 31

Moving on to step 5:
The number 31 fits into 173 5 times, leaving a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 2625.0
If we take 155 away from 173, we end up with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 31

Advancing to step 6:
The number 31 fits into 183 5 times, leaving a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 26255.0
Subtract 155 from 183 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 26255.9
Subtract 279 from 280 to 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.

Step 8:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 26255.9
The remainder is 10 after subtracting 0 from 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.
Put 3 as the next digit of the answer. 
Result so far: 26255.903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 26255.9032
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.

Step 11:
31 goes into 80 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 26255.90322
Subtracting 62 from 80 leaves us 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.

After the division, we end up with 26255.90322 and a remainder of 1.8e-05.
