72102802 ÷ 491 
We want to figure out the number of times 72102802 can be divided by 491.

Moving on to step 1:
When dividing 7 by 491, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 491

Moving on to step 2:
491 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 491

Let's proceed to step 3:
491 can be fit into 721 1 times, resulting in a remainder of 230.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 491 away from 721, we end up with 230.
Fetch the next digit (0) from the dividend, attach it to 230 and continue: 2300 / 491

On to step 4:
491 goes into 2300 4 times with a remainder of 336.
The next digit of our result is 4. 
Result so far: 14.0
If we take 1964 away from 2300, we end up with 336.
Grab the next digit (2) from the dividend, add it to 336, then carry on: 3362 / 491

On to step 5:
491 goes into 3362 6 times with a remainder of 416.
The next digit of our result is 6. 
Result so far: 146.0
If we take 2946 away from 3362, we end up with 416.
Include the next digit (8) from the dividend after 416, then repeat: 4168 / 491

Let's proceed to step 6:
The number 491 fits into 4168 8 times, leaving a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 1468.0
Subtract 3928 from 4168 to get 240.
Include the next digit (0) from the dividend after 240, then repeat: 2400 / 491

Going ahead to step 7:
The number 491 fits into 2400 4 times, leaving a remainder of 436.
Record the quotient 4 as the next digit in the result. 
Result so far: 14684.0
If we subtract 1964 from 2400, we get 436.
Bring next digit (2) of the dividend behind the 436 and repeat the process: 4362 / 491

Advancing to step 8:
When dividing 4362 by 491, we get 8 with a remainder of 434.
The next digit of our result is 8. 
Result so far: 146848.0
Subtract 3928 from 4362 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 9:
491 goes into 4340 8 times with a remainder of 412.
The number 8 becomes the next digit in our result. 
Result so far: 146848.8
If we take 3928 away from 4340, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 10:
The number 491 fits into 4120 8 times, leaving a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 146848.88
The remainder is 192 after subtracting 3928 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 146848.88 with a remaining 0.192.
