13509281 ÷ 918 
Our goal is to divide 13509281 by 918.

Let's proceed to step 1:
When dividing 1 by 918, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 918

Advancing to step 2:
The number 918 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 918

Step 3:
918 can be fit into 135 0 times, resulting in a remainder of 135.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 135, we get 135.
Bring next digit (0) of the dividend behind the 135 and repeat the process: 1350 / 918

Step 4:
When dividing 1350 by 918, we get 1 with a remainder of 432.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 918 from 1350 leaves us with 432.
Grab the next digit (9) from the dividend, add it to 432, then carry on: 4329 / 918

Step 5:
The number 918 fits into 4329 4 times, leaving a remainder of 657.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 657 after subtracting 3672 from 4329.
Append the next digit (2) from the dividend to 657 and continue with: 6572 / 918

Let's proceed to step 6:
918 can be fit into 6572 7 times, resulting in a remainder of 146.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
The remainder is 146 after subtracting 6426 from 6572.
Bring next digit (8) of the dividend behind the 146 and repeat the process: 1468 / 918

On to step 7:
918 can be fit into 1468 1 times, resulting in a remainder of 550.
Write down 1 as next digit of the result. 
Result so far: 1471.0
If we take 918 away from 1468, we end up with 550.
Grab the next digit (1) from the dividend, add it to 550, then carry on: 5501 / 918

Moving on to step 8:
The number 918 fits into 5501 5 times, leaving a remainder of 911.
Put 5 as the next digit of the answer. 
Result so far: 14715.0
The remainder is 911 after subtracting 4590 from 5501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9110, and continue the process.

Moving on to step 9:
918 can be fit into 9110 9 times, resulting in a remainder of 848.
Write down 9 as next digit of the result. 
Result so far: 14715.9
Subtracting 8262 from 9110 leaves us with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Advancing to step 10:
918 can be fit into 8480 9 times, resulting in a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 14715.99
Deduct 8262 from 8480 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final outcome is 14715.99, with a leftover of 0.218.
