71781931 ÷ 491 
Let's see how many times 491 fits into 71781931.

Step 1:
7 divided by 491 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 491

Advancing to step 2:
The number 491 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 491

Advancing to step 3:
491 can be fit into 717 1 times, resulting in a remainder of 226.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 491 from 717 leaves us with 226.
Grab the next digit (8) from the dividend, add it to 226, then carry on: 2268 / 491

Let's proceed to step 4:
If we divide 2268 by 491, we get 4 and a remainder of 304.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 1964 away from 2268, we end up with 304.
Include the next digit (1) from the dividend after 304, then repeat: 3041 / 491

Step 5:
When dividing 3041 by 491, we get 6 with a remainder of 95.
The next digit of our result is 6. 
Result so far: 146.0
The remainder is 95 after subtracting 2946 from 3041.
Grab the next digit (9) from the dividend, add it to 95, then carry on: 959 / 491

Going ahead to step 6:
The number 491 fits into 959 1 times, leaving a remainder of 468.
Record the quotient 1 as the next digit in the result. 
Result so far: 1461.0
The remainder is 468 after subtracting 491 from 959.
Include the next digit (3) from the dividend after 468, then repeat: 4683 / 491

Going ahead to step 7:
The number 491 fits into 4683 9 times, leaving a remainder of 264.
Use 9 as the next digit of our solution. 
Result so far: 14619.0
Deduct 4419 from 4683 and we're left with 264.
Take the next digit (1) from the dividend and append it to 264, then repeat: 2641 / 491

Going ahead to step 8:
491 goes into 2641 5 times with a remainder of 186.
The next digit of our result is 5. 
Result so far: 146195.0
Deduct 2455 from 2641 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 9:
The number 491 fits into 1860 3 times, leaving a remainder of 387.
Use 3 as the next digit of our solution. 
Result so far: 146195.3
Deduct 1473 from 1860 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Let's proceed to step 10:
If we divide 3870 by 491, we get 7 and a remainder of 433.
Put 7 as the next digit of the answer. 
Result so far: 146195.37
Subtract 3437 from 3870 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Going ahead to step 11:
4330 divided by 491 is 8 with a remainder of 402.
The number 8 becomes the next digit in our result. 
Result so far: 146195.378
Subtracting 3928 from 4330 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 12:
491 goes into 4020 8 times with a remainder of 92.
The next digit of our result is 8. 
Result so far: 146195.3788
If we take 3928 away from 4020, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

In conclusion, the division gives 146195.3788 with a balance of 0.00092.
