Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 26

On to step 2:
69 divided by 26 is 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 52 from 69 to get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 26

Advancing to step 3:
26 can be fit into 172 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 156 away from 172, we end up with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 26

Step 4:
The number 26 fits into 164 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 266.0
Subtract 156 from 164 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 26

Advancing to step 5:
If we divide 87 by 26, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 2663.0
The remainder is 9 after subtracting 78 from 87.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 26

Advancing to step 6:
When dividing 94 by 26, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 26633.0
If we take 78 away from 94, we end up with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 26

On to step 7:
165 divided by 26 is 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 266336.0
If we take 156 away from 165, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 26

Let's proceed to step 8:
26 can be fit into 93 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 2663363.0
Subtract 78 from 93 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
150 divided by 26 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2663363.5
If we take 130 away from 150, we end up 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.

Moving on to step 10:
When dividing 200 by 26, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 2663363.57
Subtracting 182 from 200 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
26 can be fit into 180 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 2663363.576
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
The number 26 fits into 240 9 times, leaving a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 2663363.5769
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
If we divide 60 by 26, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2663363.57692
Deduct 52 from 60 and we're left 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.

Step 14:
26 goes into 80 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 2663363.576923
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 15:
26 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2663363.576923
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.

Step 16:
26 goes into 200 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 2663363.57692307
If we take 182 away from 200, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 2663363.57692307 with a remaining 1.8e-08.
