415320 divided by 31 
Let's see how many times 31 fits into 415320.

Advancing to step 1:
4 divided by 31 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 31

On to step 2:
When dividing 41 by 31, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 31 from 41 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 31

On to step 3:
31 can be fit into 105 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 93 away from 105, we end up with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 31

Step 4:
When dividing 123 by 31, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 133.0
If we subtract 93 from 123, we get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 31

Going ahead to step 5:
When dividing 302 by 31, we get 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 1339.0
The remainder is 23 after subtracting 279 from 302.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 31

Let's proceed to step 6:
230 divided by 31 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 13397.0
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
When dividing 130 by 31, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 13397.4
Subtract 124 from 130 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 31, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 13397.41
If we subtract 31 from 60, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
The number 31 fits into 290 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 13397.419
Subtracting 279 from 290 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
The number 31 fits into 110 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 13397.4193
Subtract 93 from 110 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
If we divide 170 by 31, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13397.41935
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
When dividing 150 by 31, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 13397.419354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
If we divide 260 by 31, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 13397.4193548
If we subtract 248 from 260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 13397.41935483
Deduct 93 from 120 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 13397.41935483 and a remainder of 2.7e-08.
