31515 ÷ 92 
We're looking to find how many times 92 goes into 31515.

Step 1:
When dividing 3 by 92, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 92

Going ahead to step 2:
92 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 92

Moving on to step 3:
92 goes into 315 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 276 from 315 leaves us with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 92

Step 4:
If we divide 391 by 92, we get 4 and a remainder of 23.
The next digit of our result is 4. 
Result so far: 34.0
If we take 368 away from 391, we end up with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 92

Going ahead to step 5:
92 can be fit into 235 2 times, resulting in a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 342.0
If we take 184 away from 235, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 6:
When dividing 510 by 92, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 342.5
Deduct 460 from 510 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
500 divided by 92 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 342.55
Deduct 460 from 500 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 342.55, and the remainder is 0.04.
