53515803 divided by 11 
Our goal is to divide 53515803 by 11.

Going ahead to step 1:
11 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 11

Moving on to step 2:
11 goes into 53 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 44 from 53, we get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 11

On to step 3:
When dividing 95 by 11, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 88 from 95 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 11

Going ahead to step 4:
When dividing 71 by 11, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 486.0
If we subtract 66 from 71, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 11

On to step 5:
55 divided by 11 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4865.0
The remainder is 0 after subtracting 55 from 55.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 11

Moving on to step 6:
If we divide 8 by 11, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 48650.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 11

Let's proceed to step 7:
11 goes into 80 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 486507.0
The remainder is 3 after subtracting 77 from 80.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 11

Moving on to step 8:
11 can be fit into 33 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 4865073.0
The remainder is 0 after subtracting 33 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 11, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4865073.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
11 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4865073.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4865073.0 with a remaining 0.0.
