242521 ÷ 13 
We're looking to find how many times 13 goes into 242521.

Going ahead to step 1:
If we divide 2 by 13, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 13

Moving on to step 2:
24 divided by 13 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 11 after subtracting 13 from 24.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 13

Step 3:
If we divide 112 by 13, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 104 from 112 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 13

Step 4:
85 divided by 13 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 186.0
If we subtract 78 from 85, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 13

Going ahead to step 5:
The number 13 fits into 72 5 times, leaving a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 1865.0
Subtracting 65 from 72 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 13

Step 6:
The number 13 fits into 71 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 18655.0
Subtract 65 from 71 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.

Moving on to step 7:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 18655.4
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 18655.46
Subtracting 78 from 80 leaves us 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.

Advancing to step 9:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 18655.461
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.

Going ahead to step 10:
If we divide 70 by 13, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 18655.4615
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.

Moving on to step 11:
When dividing 50 by 13, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 18655.46153
Subtracting 39 from 50 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.

Moving on to step 12:
13 goes into 110 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 18655.461538
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.

On to step 13:
If we divide 60 by 13, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 18655.4615384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
When dividing 80 by 13, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 18655.46153846
If we take 78 away from 80, we end up 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.

In conclusion, the division gives 18655.46153846 with a balance of 2e-09.
