638280 divided by 26 
We want to figure out the number of times 638280 can be divided by 26.

Going ahead to step 1:
6 divided by 26 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 26

Going ahead to step 2:
If we divide 63 by 26, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 52 from 63, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 26

Let's proceed to step 3:
When dividing 118 by 26, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 104 from 118, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 26

On to step 4:
If we divide 142 by 26, we get 5 and a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.0
Subtract 130 from 142 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 26

Step 5:
The number 26 fits into 128 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 2454.0
The remainder is 24 after subtracting 104 from 128.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 26

Let's proceed to step 6:
26 can be fit into 240 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 24549.0
Subtracting 234 from 240 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 7:
26 goes into 60 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 24549.2
If we take 52 away from 60, we end up 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 8:
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: 24549.23
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.

Moving on to step 9:
If we divide 20 by 26, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 24549.23
If we take 0 away from 20, we end up 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.

Advancing to step 10:
The number 26 fits into 200 7 times, leaving a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 24549.2307
If we subtract 182 from 200, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
When dividing 180 by 26, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 24549.23076
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.

On to step 12:
26 goes into 240 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 24549.230769
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 13:
The number 26 fits into 60 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 24549.2307692
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.

Let's proceed to step 14:
When dividing 80 by 26, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 24549.23076923
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.

The final outcome is 24549.23076923, with a leftover of 2e-09.
