Let's divide 917390 by 31
We're looking to find how many times 31 goes into 917390.

Going ahead to step 1:
If we divide 9 by 31, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 31

Moving on to step 2:
If we divide 91 by 31, we get 2 and a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 62 from 91, we get 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 31

Let's proceed to step 3:
31 can be fit into 297 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 279 from 297 leaves us with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 31

Let's proceed to step 4:
If we divide 183 by 31, we get 5 and a remainder of 28.
The next digit of our result is 5. 
Result so far: 295.0
Subtracting 155 from 183 leaves us with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 31

Advancing to step 5:
31 goes into 289 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 2959.0
Subtracting 279 from 289 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 31

Step 6:
If we divide 100 by 31, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 29593.0
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.

Advancing to step 7:
If we divide 70 by 31, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 29593.2
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 8:
If we divide 80 by 31, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 29593.22
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 29593.22 and a remainder of 0.018.
