515278 ÷ 26 
Let's see how many times 26 fits into 515278.

Moving on to step 1:
The number 26 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 26

Step 2:
If we divide 51 by 26, we get 1 and a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 26 from 51 to get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 26

On to step 3:
If we divide 255 by 26, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 234 from 255 and we're left with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 26

On to step 4:
26 can be fit into 212 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 198.0
Subtract 208 from 212 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 26

Moving on to step 5:
26 can be fit into 47 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1981.0
Subtract 26 from 47 to get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 26

On to step 6:
The number 26 fits into 218 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 19818.0
If we take 208 away from 218, we end up 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.

Let's proceed to step 7:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 19818.3
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.

Going ahead to 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: 19818.38
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.

Moving on to step 9:
26 goes into 120 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 19818.384
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.

Advancing to step 10:
If we divide 160 by 26, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 19818.3846
Subtracting 156 from 160 leaves us 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.

Advancing to step 11:
26 goes into 40 1 times with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 19818.38461
If we take 26 away from 40, we end up 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.

Let's proceed 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: 19818.384615
Deduct 130 from 140 and we're left 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.

On to step 13:
100 divided by 26 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 19818.3846153
Subtracting 78 from 100 leaves us 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 14:
26 goes into 220 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 19818.38461538
If we subtract 208 from 220, we 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.

After the division, we end up with 19818.38461538 and a remainder of 1.2e-08.
