We look at the division of 511989 by 26 
Let's see how many times 26 fits into 511989.

Moving on to step 1:
The number 26 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 26

Moving on to step 2:
26 can be fit into 51 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 26 away from 51, we end up with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 26

Moving on to step 3:
The number 26 fits into 251 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 234 from 251 leaves us with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 26

Moving on to step 4:
26 goes into 179 6 times with a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
Subtracting 156 from 179 leaves us with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 26

Let's proceed to step 5:
26 goes into 238 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1969.0
The remainder is 4 after subtracting 234 from 238.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 26

On to step 6:
When dividing 49 by 26, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 19691.0
Subtract 26 from 49 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
If we divide 230 by 26, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 19691.8
Subtract 208 from 230 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
The number 26 fits into 220 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 19691.88
Deduct 208 from 220 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 19691.88 and a remainder of 0.012.
