We look at the division of 642744 by 26 
We want to figure out the number of times 642744 can be divided by 26.

Advancing to step 1:
26 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 26

Moving on to step 2:
64 divided by 26 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 52 from 64, we get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 26

On to step 3:
If we divide 122 by 26, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 104 from 122, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 26

Step 4:
187 divided by 26 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 247.0
Subtract 182 from 187 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 26

On to step 5:
26 can be fit into 54 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2472.0
Subtracting 52 from 54 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 26

On to step 6:
If we divide 24 by 26, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 24720.0
Deduct 0 from 24 and we're left 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.

Let's proceed to step 7:
240 divided by 26 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 24720.9
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 8:
26 goes into 60 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 24720.92
Deduct 52 from 60 and we're left 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.

Advancing to step 9:
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: 24720.923
The remainder is 2 after subtracting 78 from 80.
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 10:
The number 26 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 24720.923
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.

Advancing to step 11:
26 goes into 200 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 24720.92307
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.

On to step 12:
180 divided by 26 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 24720.923076
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.

Let's proceed to step 13:
If we divide 240 by 26, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 24720.9230769
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 14:
26 can be fit into 60 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 24720.92307692
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.

After the division, we end up with 24720.92307692 and a remainder of 8e-09.
