We look at the division of 809438 by 31 
We're looking to find how many times 31 goes into 809438.

Step 1:
31 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 31

On to step 2:
When dividing 80 by 31, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 62 from 80, we get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 31

Going ahead to step 3:
31 can be fit into 189 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 186 from 189 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 31

Let's proceed to step 4:
When dividing 34 by 31, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 261.0
Deduct 31 from 34 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 31

Going ahead to step 5:
When dividing 33 by 31, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 2611.0
Subtracting 31 from 33 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 31

Advancing to step 6:
31 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 26110.0
If we take 0 away from 28, we end up 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.

Going ahead to step 7:
When dividing 280 by 31, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 26110.9
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 26110.9
Deduct 0 from 10 and we're left 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.

Step 9:
When dividing 100 by 31, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 26110.903
If we take 93 away from 100, we end up 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.

Moving on to step 10:
31 goes into 70 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 26110.9032
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:
80 divided by 31 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 26110.90322
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.

Our division results in 26110.90322 with a remaining 1.8e-05.
