Let's divide 81102391 by 26
We're looking to find how many times 26 goes into 81102391.

On to step 1:
If we divide 8 by 26, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 26

Advancing to step 2:
When dividing 81 by 26, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 78 from 81 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 26

Let's proceed to step 3:
26 goes into 31 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 26 from 31 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 26

Let's proceed to step 4:
26 goes into 50 1 times with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 311.0
Subtract 26 from 50 to get 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 26

Let's proceed to step 5:
242 divided by 26 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 3119.0
Subtracting 234 from 242 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 26

Advancing to step 6:
83 divided by 26 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 31193.0
Subtracting 78 from 83 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 26

Step 7:
If we divide 59 by 26, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 311932.0
Subtracting 52 from 59 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 26

Going ahead to step 8:
The number 26 fits into 71 2 times, leaving a remainder of 19.
The next digit of our result is 2. 
Result so far: 3119322.0
If we subtract 52 from 71, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
26 goes into 190 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 3119322.7
Deduct 182 from 190 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.

On to step 10:
When dividing 80 by 26, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3119322.73
If we subtract 78 from 80, we 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.

Advancing to step 11:
When dividing 20 by 26, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3119322.73
Deduct 0 from 20 and we're left 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 12:
26 goes into 200 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3119322.7307
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.

Going ahead to step 13:
When dividing 180 by 26, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 3119322.73076
Subtract 156 from 180 to 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.

Step 14:
26 goes into 240 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 3119322.730769
Subtracting 234 from 240 leaves us 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.

Step 15:
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: 3119322.7307692
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3119322.73076923
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 3119322.73076923, and the remainder is 2e-09.
