We look at the division of 515393 by 26 
Our goal is to divide 515393 by 26.

Moving on to step 1:
26 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 26

Advancing to step 2:
26 can be fit into 51 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 25 after subtracting 26 from 51.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 26

Advancing to step 3:
26 goes into 255 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 21 after subtracting 234 from 255.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 26

Going ahead to step 4:
If we divide 213 by 26, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
If we subtract 208 from 213, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 26

Moving on to step 5:
59 divided by 26 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 1982.0
Deduct 52 from 59 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 26

Let's proceed to step 6:
26 goes into 73 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 19822.0
If we take 52 away from 73, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
26 can be fit into 210 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 19822.8
Subtracting 208 from 210 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.

Step 8:
20 divided by 26 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 19822.8
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.

Step 9:
If we divide 200 by 26, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 19822.807
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.

Going ahead to step 10:
180 divided by 26 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 19822.8076
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.

Going ahead to step 11:
240 divided by 26 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 19822.80769
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.

Moving on to step 12:
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: 19822.807692
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.

Let's proceed to step 13:
When dividing 80 by 26, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 19822.8076923
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.

Moving on to step 14:
If we divide 20 by 26, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 19822.8076923
If we take 0 away from 20, we end up 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.

After the division, we end up with 19822.8076923 and a remainder of 2e-08.
