We look at the division of 642501 by 26 
Let's see how many times 26 fits into 642501.

Going ahead to step 1:
26 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 26

Step 2:
When dividing 64 by 26, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 52 from 64 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 26

Let's proceed to step 3:
26 goes into 122 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 18 after subtracting 104 from 122.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 26

Let's proceed to step 4:
If we divide 185 by 26, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 247.0
The remainder is 3 after subtracting 182 from 185.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 26

Advancing to step 5:
26 can be fit into 30 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 2471.0
If we take 26 away from 30, we end up with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 26

Advancing to step 6:
The number 26 fits into 41 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 24711.0
If we take 26 away from 41, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
26 can be fit into 150 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 24711.5
Deduct 130 from 150 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.

Advancing to step 8:
200 divided by 26 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 24711.57
Subtract 182 from 200 to 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.

Advancing to step 9:
The number 26 fits into 180 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 24711.576
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.

Step 10:
26 goes into 240 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 24711.5769
If we take 234 away from 240, we end up 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.

Advancing to step 11:
26 goes into 60 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 24711.57692
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.

On to step 12:
The number 26 fits into 80 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 24711.576923
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.

Let's proceed to step 13:
If we divide 20 by 26, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 24711.576923
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
When dividing 200 by 26, we get 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 24711.57692307
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.

Our division results in 24711.57692307 with a remaining 1.8e-08.
