310531 divided by 15 
We're looking to find how many times 15 goes into 310531.

Going ahead to step 1:
3 divided by 15 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 15

Step 2:
15 can be fit into 31 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 1 after subtracting 30 from 31.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 15

Advancing to step 3:
When dividing 10 by 15, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 15

Going ahead to step 4:
105 divided by 15 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 207.0
If we take 105 away from 105, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 15

Moving on to step 5:
The number 15 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 2070.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 15

Going ahead to step 6:
If we divide 31 by 15, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 20702.0
If we subtract 30 from 31, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
15 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 20702.0
If we subtract 0 from 10, we get 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 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 20702.06
If we take 90 away from 100, we end up 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.

Let's proceed to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 20702.066
Subtracting 90 from 100 leaves us 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.

Our division results in 20702.066 with a remaining 0.001.
