We look at the division of 521810 by 26 
Let's see how many times 26 fits into 521810.

Advancing to step 1:
26 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 26

Let's proceed to step 2:
26 can be fit into 52 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 52 from 52.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 26

Advancing to step 3:
When dividing 1 by 26, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 26

Step 4:
26 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 26

Let's proceed to step 5:
26 goes into 181 6 times with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 2006.0
Subtracting 156 from 181 leaves us with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 26

Moving on to step 6:
The number 26 fits into 250 9 times, leaving a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 20069.0
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
26 goes into 160 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 20069.6
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 26, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 20069.61
The remainder is 14 after subtracting 26 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
26 can be fit into 140 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 20069.615
Subtract 130 from 140 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 26, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 20069.6153
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 20069.61538
Subtracting 208 from 220 leaves us 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.

Going ahead to step 12:
If we divide 120 by 26, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 20069.615384
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
160 divided by 26 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 20069.6153846
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
40 divided by 26 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 20069.61538461
Subtracting 26 from 40 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 20069.61538461 with a balance of 1.4e-08.
