31235 ÷ 3 
We're looking to find how many times 3 goes into 31235.

Moving on to step 1:
3 divided by 3 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 3 from 3 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

On to step 2:
If we divide 1 by 3, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 3

Advancing to step 3:
The number 3 fits into 12 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 12 from 12, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Let's proceed to step 4:
The number 3 fits into 3 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1041.0
If we subtract 3 from 3, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Advancing to step 5:
3 goes into 5 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 10411.0
The remainder is 2 after subtracting 3 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 10411.6
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 10411.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 10411.66 with a remaining 0.002.
