26581825 ÷ 18 
Let's see how many times 18 fits into 26581825.

Step 1:
2 divided by 18 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 18

Step 2:
26 divided by 18 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 18 from 26, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 18

Moving on to step 3:
18 goes into 85 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 72 from 85 leaves us with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 18

Let's proceed to step 4:
The number 18 fits into 138 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
If we take 126 away from 138, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 18

Moving on to step 5:
If we divide 121 by 18, we get 6 and a remainder of 13.
The next digit of our result is 6. 
Result so far: 1476.0
Subtracting 108 from 121 leaves us with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 18

Going ahead to step 6:
18 goes into 138 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 14767.0
Subtracting 126 from 138 leaves us with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 18

Going ahead to step 7:
18 can be fit into 122 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 147676.0
If we subtract 108 from 122, we get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 18

Advancing to step 8:
When dividing 145 by 18, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1476768.0
Subtract 144 from 145 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1476768.0
Deduct 0 from 10 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 10:
When dividing 100 by 18, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1476768.05
Subtracting 90 from 100 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.

Moving on to step 11:
18 goes into 100 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 1476768.055
Subtract 90 from 100 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.

The final result is 1476768.055 with a remainder of 0.001.
