53515602 divided by 108 
We want to figure out the number of times 53515602 can be divided by 108.

Going ahead to step 1:
108 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 108

Advancing to step 2:
The number 108 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 108

Going ahead to step 3:
108 can be fit into 535 4 times, resulting in a remainder of 103.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 103 after subtracting 432 from 535.
Bring next digit (1) of the dividend behind the 103 and repeat the process: 1031 / 108

Moving on to step 4:
The number 108 fits into 1031 9 times, leaving a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 972 away from 1031, we end up with 59.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 108

Advancing to step 5:
The number 108 fits into 595 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 495.0
The remainder is 55 after subtracting 540 from 595.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 108

Going ahead to step 6:
108 can be fit into 556 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 4955.0
Subtracting 540 from 556 leaves us with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 108

On to step 7:
108 goes into 160 1 times with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 49551.0
The remainder is 52 after subtracting 108 from 160.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 108

Advancing to step 8:
The number 108 fits into 522 4 times, leaving a remainder of 90.
The next digit of our result is 4. 
Result so far: 495514.0
If we take 432 away from 522, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
108 can be fit into 900 8 times, resulting in a remainder of 36.
The next digit of our result is 8. 
Result so far: 495514.8
If we subtract 864 from 900, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
The number 108 fits into 360 3 times, leaving a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 495514.83
If we subtract 324 from 360, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
108 goes into 360 3 times with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 495514.833
Subtracting 324 from 360 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 495514.833 with a remainder of 0.0036.
