We look at the division of 638493 by 26 
Our goal is to divide 638493 by 26.

On to step 1:
26 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 26

Step 2:
26 goes into 63 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 52 from 63, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 26

Step 3:
26 can be fit into 118 4 times, resulting in 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.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 26

Let's proceed to step 4:
If we divide 144 by 26, we get 5 and a remainder of 14.
The next digit of our result is 5. 
Result so far: 245.0
The remainder is 14 after subtracting 130 from 144.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 26

Advancing to step 5:
26 goes into 149 5 times with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 2455.0
The remainder is 19 after subtracting 130 from 149.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 26

Advancing to step 6:
If we divide 193 by 26, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 24557.0
If we subtract 182 from 193, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
26 can be fit into 110 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 24557.4
If we take 104 away from 110, 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.

Let's proceed to step 8:
When dividing 60 by 26, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 24557.42
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.

On to step 9:
When dividing 80 by 26, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 24557.423
Subtracting 78 from 80 leaves us with 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 10:
20 divided by 26 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 24557.423
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:
The number 26 fits into 200 7 times, leaving a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 24557.42307
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.

Let's proceed to step 12:
If we divide 180 by 26, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 24557.423076
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.

Advancing to step 13:
If we divide 240 by 26, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 24557.4230769
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 14:
60 divided by 26 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 24557.42307692
Subtract 52 from 60 to get 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 24557.42307692 and a remainder of 8e-09.
