We look at the division of 645624 by 26 
We're looking to find how many times 26 goes into 645624.

Step 1:
6 divided by 26 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 26

Step 2:
26 can be fit into 64 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 52 from 64 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 26

Step 3:
When dividing 125 by 26, we get 4 with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 21 after subtracting 104 from 125.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 26

Advancing to step 4:
When dividing 216 by 26, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 248.0
Subtracting 208 from 216 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 26

Let's proceed to step 5:
The number 26 fits into 82 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 2483.0
Subtract 78 from 82 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 26

Let's proceed to step 6:
The number 26 fits into 44 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 24831.0
Subtracting 26 from 44 leaves us 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 7:
When dividing 180 by 26, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 24831.6
If we take 156 away from 180, we end up 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.

Moving on to step 8:
When dividing 240 by 26, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 24831.69
Deduct 234 from 240 and we're left 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.

Step 9:
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: 24831.692
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.

On to step 10:
80 divided by 26 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 24831.6923
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.

On to step 11:
When dividing 20 by 26, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 24831.6923
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.

Going ahead to step 12:
26 goes into 200 7 times with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 24831.692307
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.

On to step 13:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 24831.6923076
The remainder is 24 after subtracting 156 from 180.
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 14:
240 divided by 26 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 24831.69230769
Deduct 234 from 240 and we're left 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.

After the division, we end up with 24831.69230769 and a remainder of 6e-09.
