We're dividing 510427 by 26 
Let's see how many times 26 fits into 510427.

Going ahead to step 1:
When dividing 5 by 26, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 26

Step 2:
51 divided by 26 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 26 from 51 to get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 26

Let's proceed to step 3:
If we divide 250 by 26, we get 9 and a remainder of 16.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 234 from 250, we get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 26

Advancing to step 4:
26 goes into 164 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
If we take 156 away from 164, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 26

Let's proceed to step 5:
26 goes into 82 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 1963.0
Subtract 78 from 82 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 26

On to step 6:
The number 26 fits into 47 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 19631.0
Deduct 26 from 47 and we're left 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.

Going ahead 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: 19631.8
Subtract 208 from 210 to 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.

Moving on to step 8:
26 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19631.8
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 9:
If we divide 200 by 26, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 19631.807
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.
Write down 6 as next digit of the result. 
Result so far: 19631.8076
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.

Advancing to step 11:
26 goes into 240 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 19631.80769
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.

Going ahead to step 12:
The number 26 fits into 60 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 19631.807692
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 13:
The number 26 fits into 80 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 19631.8076923
Subtract 78 from 80 to 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.

Moving on to step 14:
The number 26 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 19631.8076923
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 19631.8076923, with a leftover of 2e-08.
