515638 ÷ 26 
Let's see how many times 26 fits into 515638.

Step 1:
26 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 26

Going ahead to step 2:
26 can be fit into 51 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 26 from 51 leaves us with 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 26

Advancing to step 3:
When dividing 255 by 26, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 234 from 255 and we're left with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 26

On to step 4:
26 can be fit into 216 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
Deduct 208 from 216 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 26

Moving on to step 5:
If we divide 83 by 26, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 1983.0
Subtract 78 from 83 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 26

Going ahead to step 6:
26 can be fit into 58 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 19832.0
Subtract 52 from 58 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.

Going ahead to step 7:
If we divide 60 by 26, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 19832.2
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.

On to step 8:
26 goes into 80 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 19832.23
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.

Going ahead to step 9:
26 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19832.23
Subtracting 0 from 20 leaves us 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.

Step 10:
The number 26 fits into 200 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 19832.2307
If we take 182 away from 200, we end up 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 11:
180 divided by 26 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 19832.23076
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.

Going ahead to step 12:
The number 26 fits into 240 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 19832.230769
Subtract 234 from 240 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.

Let's proceed to step 13:
If we divide 60 by 26, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 19832.2307692
Subtract 52 from 60 to get 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 14:
If we divide 80 by 26, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 19832.23076923
If we subtract 78 from 80, we 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.

Our division results in 19832.23076923 with a remaining 2e-09.
