315600 divided by 31 
We're looking to find how many times 31 goes into 315600.

On to step 1:
3 divided by 31 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 31

Moving on to step 2:
31 divided by 31 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 31 from 31.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 31

Moving on to step 3:
If we divide 5 by 31, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 5 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 31

On to step 4:
The number 31 fits into 56 1 times, leaving a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Subtract 31 from 56 to get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 31

On to step 5:
If we divide 250 by 31, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1018.0
Deduct 248 from 250 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 31

Moving on to step 6:
The number 31 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 10180.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
200 divided by 31 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 10180.6
If we take 186 away from 200, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 31 fits into 140 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 10180.64
Subtracting 124 from 140 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 31, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 10180.645
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
31 can be fit into 50 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 10180.6451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 10180.64516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
40 divided by 31 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 10180.645161
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
When dividing 90 by 31, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 10180.6451612
Subtract 62 from 90 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
31 can be fit into 280 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 10180.64516129
Subtract 279 from 280 to 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.

Our division results in 10180.64516129 with a remaining 1e-09.
