We divide 903953 by 31
Let's see how many times 31 fits into 903953.

Going ahead to step 1:
The number 31 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 31

Step 2:
When dividing 90 by 31, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 62 from 90, we get 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 31

Let's proceed to step 3:
31 goes into 283 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 4 after subtracting 279 from 283.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 31

Moving on to step 4:
The number 31 fits into 49 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
Subtract 31 from 49 to get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 31

On to step 5:
31 can be fit into 185 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2915.0
If we take 155 away from 185, we end up with 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 31

Let's proceed to step 6:
If we divide 303 by 31, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 29159.0
Deduct 279 from 303 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
If we divide 240 by 31, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 29159.7
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
230 divided by 31 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 29159.77
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 29159.77 with a remainder of 0.013.
