310837 ÷ 15 
We're looking to find how many times 15 goes into 310837.

Step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 15

Let's proceed to step 2:
15 can be fit into 31 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 30 from 31 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 15

Going ahead to step 3:
The number 15 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 15

Advancing to step 4:
15 can be fit into 108 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 207.0
If we take 105 away from 108, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 15

Advancing to step 5:
The number 15 fits into 33 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2072.0
If we take 30 away from 33, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 15

On to step 6:
37 divided by 15 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 20722.0
Subtracting 30 from 37 leaves us 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.

Let's proceed to step 7:
When dividing 70 by 15, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 20722.4
Deduct 60 from 70 and we're left 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.

Step 8:
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: 20722.46
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.

Going ahead to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 20722.466
Subtract 90 from 100 to 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.

The quotient of the division is 20722.466, and the remainder is 0.001.
