We look at the division of 72768534 by 636 
We want to divide 72768534 by 636.

Let's proceed to step 1:
The number 636 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 636

On to step 2:
When dividing 72 by 636, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (7) from the dividend, attach it to 72 and continue: 727 / 636

Step 3:
636 goes into 727 1 times with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 636 from 727 to get 91.
Fetch the next digit (6) from the dividend, attach it to 91 and continue: 916 / 636

Advancing to step 4:
If we divide 916 by 636, we get 1 and a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 636 away from 916, we end up with 280.
Include the next digit (8) from the dividend after 280, then repeat: 2808 / 636

Moving on to step 5:
When dividing 2808 by 636, we get 4 with a remainder of 264.
The next digit of our result is 4. 
Result so far: 114.0
Deduct 2544 from 2808 and we're left with 264.
Include the next digit (5) from the dividend after 264, then repeat: 2645 / 636

Advancing to step 6:
If we divide 2645 by 636, we get 4 and a remainder of 101.
The number 4 becomes the next digit in our result. 
Result so far: 1144.0
Subtract 2544 from 2645 to get 101.
Include the next digit (3) from the dividend after 101, then repeat: 1013 / 636

Let's proceed to step 7:
636 goes into 1013 1 times with a remainder of 377.
Write down 1 as next digit of the result. 
Result so far: 11441.0
If we take 636 away from 1013, we end up with 377.
Take the next digit (4) from the dividend and append it to 377, then repeat: 3774 / 636

Step 8:
The number 636 fits into 3774 5 times, leaving a remainder of 594.
The number 5 becomes the next digit in our result. 
Result so far: 114415.0
The remainder is 594 after subtracting 3180 from 3774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 9:
636 can be fit into 5940 9 times, resulting in a remainder of 216.
Put 9 as the next digit of the answer. 
Result so far: 114415.9
Deduct 5724 from 5940 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 10:
2160 divided by 636 is 3 with a remainder of 252.
Use 3 as the next digit of our solution. 
Result so far: 114415.93
Subtracting 1908 from 2160 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 11:
636 goes into 2520 3 times with a remainder of 612.
The number 3 becomes the next digit in our result. 
Result so far: 114415.933
If we subtract 1908 from 2520, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Our division results in 114415.933 with a remaining 0.0612.
