We're dividing 505580 by 26 
We want to figure out the number of times 505580 can be divided by 26.

On to step 1:
When dividing 5 by 26, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 26

Advancing to step 2:
26 can be fit into 50 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 26 away from 50, we end up with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 26

Moving on to step 3:
26 can be fit into 245 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 234 from 245 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 26

Step 4:
The number 26 fits into 115 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
If we subtract 104 from 115, we get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 26

Going ahead to step 5:
118 divided by 26 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 1944.0
Subtract 104 from 118 to get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 26

Moving on to step 6:
26 goes into 140 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 19445.0
Subtracting 130 from 140 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 26, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 19445.3
Subtract 78 from 100 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.

Moving on to step 8:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 19445.38
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
26 can be fit into 120 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 19445.384
Deduct 104 from 120 and we're left with 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 10:
160 divided by 26 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 19445.3846
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
40 divided by 26 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 19445.38461
Subtract 26 from 40 to get 14.
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 12:
140 divided by 26 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 19445.384615
The remainder is 10 after subtracting 130 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 26, we get 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 19445.3846153
If we subtract 78 from 100, we 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 14:
26 goes into 220 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 19445.38461538
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.

The final outcome is 19445.38461538, with a leftover of 1.2e-08.
