We're dividing 640608 by 26 
We want to divide 640608 by 26.

On to step 1:
If we divide 6 by 26, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 26

Step 2:
The number 26 fits into 64 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 12 after subtracting 52 from 64.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 26

Step 3:
120 divided by 26 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 16 after subtracting 104 from 120.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 26

On to step 4:
26 goes into 166 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtract 156 from 166 to get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 26

Advancing to step 5:
26 goes into 100 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 2463.0
Subtract 78 from 100 to get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 26

Moving on to step 6:
The number 26 fits into 228 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 24638.0
Subtract 208 from 228 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.

Going ahead to step 7:
26 can be fit into 200 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 24638.7
Subtracting 182 from 200 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.

Let's proceed to step 8:
The number 26 fits into 180 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 24638.76
If we subtract 156 from 180, we 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.

Let's proceed to step 9:
240 divided by 26 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 24638.769
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
60 divided by 26 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 24638.7692
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 11:
26 goes into 80 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 24638.76923
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.

Going ahead to step 12:
26 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 24638.76923
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.

On to step 13:
26 can be fit into 200 7 times, resulting in a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 24638.7692307
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.

Moving on to step 14:
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: 24638.76923076
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.

The quotient of the division is 24638.76923076, and the remainder is 2.4e-08.
