31687615 ÷ 315 
Our goal is to divide 31687615 by 315.

Moving on to step 1:
315 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 315

Going ahead to step 2:
When dividing 31 by 315, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 315

Let's proceed to step 3:
The number 315 fits into 316 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 315 from 316 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 315

Advancing to step 4:
When dividing 18 by 315, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 315

On to step 5:
187 divided by 315 is 0 with a remainder of 187.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 187 to get 187.
Take the next digit (6) from the dividend and append it to 187, then repeat: 1876 / 315

On to step 6:
When dividing 1876 by 315, we get 5 with a remainder of 301.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
The remainder is 301 after subtracting 1575 from 1876.
Bring next digit (1) of the dividend behind the 301 and repeat the process: 3011 / 315

On to step 7:
If we divide 3011 by 315, we get 9 and a remainder of 176.
Write down 9 as next digit of the result. 
Result so far: 10059.0
Deduct 2835 from 3011 and we're left with 176.
Include the next digit (5) from the dividend after 176, then repeat: 1765 / 315

Moving on to step 8:
315 goes into 1765 5 times with a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 100595.0
The remainder is 190 after subtracting 1575 from 1765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 9:
315 goes into 1900 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 100595.6
Subtracting 1890 from 1900 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.

Advancing to step 10:
315 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 100595.6
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
1000 divided by 315 is 3 with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 100595.603
If we take 945 away from 1000, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
If we divide 550 by 315, we get 1 and a remainder of 235.
Write down 1 as next digit of the result. 
Result so far: 100595.6031
Deduct 315 from 550 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 13:
2350 divided by 315 is 7 with a remainder of 145.
The next digit of our result is 7. 
Result so far: 100595.60317
The remainder is 145 after subtracting 2205 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 14:
1450 divided by 315 is 4 with a remainder of 190.
The number 4 becomes the next digit in our result. 
Result so far: 100595.603174
If we subtract 1260 from 1450, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 15:
If we divide 1900 by 315, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 100595.6031746
Deduct 1890 from 1900 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.

Let's proceed to step 16:
100 divided by 315 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 100595.6031746
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 100595.6031746, and the remainder is 1e-07.
