We look at the division of 11155535 by 504 
Let's see how many times 504 fits into 11155535.

Step 1:
If we divide 1 by 504, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 504

Going ahead to step 2:
When dividing 11 by 504, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 504

Moving on to step 3:
When dividing 111 by 504, we get 0 with a remainder of 111.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 111, we get 111.
Fetch the next digit (5) from the dividend, attach it to 111 and continue: 1115 / 504

On to step 4:
504 can be fit into 1115 2 times, resulting in a remainder of 107.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 107 after subtracting 1008 from 1115.
Include the next digit (5) from the dividend after 107, then repeat: 1075 / 504

Moving on to step 5:
If we divide 1075 by 504, we get 2 and a remainder of 67.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 67 after subtracting 1008 from 1075.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 504

Let's proceed to step 6:
When dividing 675 by 504, we get 1 with a remainder of 171.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Deduct 504 from 675 and we're left with 171.
Take the next digit (3) from the dividend and append it to 171, then repeat: 1713 / 504

Advancing to step 7:
If we divide 1713 by 504, we get 3 and a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 2213.0
Subtracting 1512 from 1713 leaves us with 201.
Bring next digit (5) of the dividend behind the 201 and repeat the process: 2015 / 504

Moving on to step 8:
504 can be fit into 2015 3 times, resulting in a remainder of 503.
Record the quotient 3 as the next digit in the result. 
Result so far: 22133.0
Deduct 1512 from 2015 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 9:
5030 divided by 504 is 9 with a remainder of 494.
Put 9 as the next digit of the answer. 
Result so far: 22133.9
Subtracting 4536 from 5030 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 10:
When dividing 4940 by 504, we get 9 with a remainder of 404.
Record the quotient 9 as the next digit in the result. 
Result so far: 22133.99
Subtracting 4536 from 4940 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final outcome is 22133.99, with a leftover of 0.404.
