252423 ÷ 13 
Let's see how many times 13 fits into 252423.

On to step 1:
13 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 13

Let's proceed to step 2:
When dividing 25 by 13, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 13 from 25.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 13

Going ahead to step 3:
If we divide 122 by 13, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 117 from 122 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 13

Going ahead to step 4:
13 can be fit into 54 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 194.0
Subtracting 52 from 54 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 13

Let's proceed to step 5:
13 can be fit into 22 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1941.0
Subtracting 13 from 22 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 13

Let's proceed to step 6:
13 goes into 93 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 19417.0
Deduct 91 from 93 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 19417.1
The remainder is 7 after subtracting 13 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 19417.15
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 13, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 19417.153
The remainder is 11 after subtracting 39 from 50.
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:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 19417.1538
Subtracting 104 from 110 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 19417.15384
Subtracting 52 from 60 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 19417.153846
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
13 goes into 20 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 19417.1538461
Subtract 13 from 20 to get 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 14:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 19417.15384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 19417.15384615, with a leftover of 5e-09.
