21247 ÷ 26 
Let's see how many times 26 fits into 21247.

Advancing to step 1:
26 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 26

Moving on to step 2:
If we divide 21 by 26, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 26

Let's proceed to step 3:
If we divide 212 by 26, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 208 from 212 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 26

Step 4:
The number 26 fits into 44 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 81.0
Deduct 26 from 44 and we're left with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 26

Step 5:
If we divide 187 by 26, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 817.0
Deduct 182 from 187 and we're left with 5.
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 6:
26 can be fit into 50 1 times, resulting in a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 817.1
The remainder is 24 after subtracting 26 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
The number 26 fits into 240 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 817.19
If we subtract 234 from 240, we 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.

Advancing to step 8:
When dividing 60 by 26, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 817.192
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 9:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 817.1923
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.

Advancing to step 10:
20 divided by 26 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 817.1923
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.

On to step 11:
The number 26 fits into 200 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 817.192307
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.

Moving on to step 12:
The number 26 fits into 180 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 817.1923076
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
When dividing 240 by 26, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 817.19230769
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.

Our division results in 817.19230769 with a remaining 6e-09.
