12539 divided by 26 
We're looking to find how many times 26 goes into 12539.

Advancing to step 1:
If we divide 1 by 26, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 26

Advancing to step 2:
If we divide 12 by 26, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 26

Step 3:
125 divided by 26 is 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 104 away from 125, we end up with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 26

Moving on to step 4:
26 goes into 213 8 times with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtracting 208 from 213 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 26

On to step 5:
When dividing 59 by 26, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 482.0
Subtract 52 from 59 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.

Moving on to step 6:
26 can be fit into 70 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 482.2
Deduct 52 from 70 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 482.26
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
26 can be fit into 240 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 482.269
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
60 divided by 26 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 482.2692
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.

Step 10:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 482.26923
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.

Let's proceed to step 11:
When dividing 20 by 26, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 482.26923
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
The number 26 fits into 200 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 482.2692307
Deduct 182 from 200 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 482.26923076
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 482.26923076 with a remainder of 2.4e-08.
