26612018 ÷ 15 
We want to divide 26612018 by 15.

Advancing to step 1:
15 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the 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 / 15

Moving on to step 2:
15 goes into 26 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 15 from 26, we get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 15

Moving on to step 3:
15 goes into 116 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 11 after subtracting 105 from 116.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 15

Moving on to step 4:
The number 15 fits into 111 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 177.0
The remainder is 6 after subtracting 105 from 111.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 15

Step 5:
When dividing 62 by 15, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 1774.0
If we subtract 60 from 62, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 15

On to step 6:
When dividing 20 by 15, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 17741.0
If we take 15 away from 20, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 15

Going ahead to step 7:
The number 15 fits into 51 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 177413.0
Subtract 45 from 51 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 15

Moving on to step 8:
The number 15 fits into 68 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1774134.0
Subtract 60 from 68 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
If we divide 80 by 15, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 1774134.5
If we take 75 away from 80, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1774134.53
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1774134.533
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 1774134.533, with a leftover of 0.0005.
