We're dividing 315455 by 13 
We're looking to find how many times 13 goes into 315455.

Moving on to step 1:
If we divide 3 by 13, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 13

Let's proceed to step 2:
The number 13 fits into 31 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 26 from 31, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 13

Going ahead to step 3:
The number 13 fits into 55 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 3 after subtracting 52 from 55.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 13

Advancing to step 4:
13 goes into 34 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 242.0
If we take 26 away from 34, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 13

Let's proceed to step 5:
13 can be fit into 85 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 2426.0
If we subtract 78 from 85, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 13

Let's proceed to step 6:
13 can be fit into 75 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 24265.0
Deduct 65 from 75 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 7:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 24265.7
Subtract 91 from 100 to 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.

Step 8:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 24265.76
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 13 fits into 120 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 24265.769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
If we divide 30 by 13, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 24265.7692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
When dividing 40 by 13, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 24265.76923
Subtract 39 from 40 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.

Going ahead to step 12:
If we divide 10 by 13, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 24265.76923
Subtract 0 from 10 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.

Advancing to step 13:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 24265.7692307
Deduct 91 from 100 and we're left with 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 14:
The number 13 fits into 90 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 24265.76923076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 24265.76923076, with a leftover of 1.2e-08.
