81776388 ÷ 491 
Let's see how many times 491 fits into 81776388.

Moving on to step 1:
If we divide 8 by 491, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 491

On to step 2:
491 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (7) from the dividend, add it to 81, then carry on: 817 / 491

Let's proceed to step 3:
491 goes into 817 1 times with a remainder of 326.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 326 after subtracting 491 from 817.
Take the next digit (7) from the dividend and append it to 326, then repeat: 3267 / 491

Going ahead to step 4:
If we divide 3267 by 491, we get 6 and a remainder of 321.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 321 after subtracting 2946 from 3267.
Include the next digit (6) from the dividend after 321, then repeat: 3216 / 491

Step 5:
491 goes into 3216 6 times with a remainder of 270.
The next digit of our result is 6. 
Result so far: 166.0
If we take 2946 away from 3216, we end up with 270.
Include the next digit (3) from the dividend after 270, then repeat: 2703 / 491

Moving on to step 6:
The number 491 fits into 2703 5 times, leaving a remainder of 248.
Use 5 as the next digit of our solution. 
Result so far: 1665.0
The remainder is 248 after subtracting 2455 from 2703.
Include the next digit (8) from the dividend after 248, then repeat: 2488 / 491

Going ahead to step 7:
491 can be fit into 2488 5 times, resulting in a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 16655.0
If we subtract 2455 from 2488, we get 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 491

Moving on to step 8:
If we divide 338 by 491, we get 0 and a remainder of 338.
Record the quotient 0 as the next digit in the result. 
Result so far: 166550.0
If we take 0 away from 338, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 9:
The number 491 fits into 3380 6 times, leaving a remainder of 434.
The next digit of our result is 6. 
Result so far: 166550.6
If we take 2946 away from 3380, we end up with 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 10:
4340 divided by 491 is 8 with a remainder of 412.
Use 8 as the next digit of our solution. 
Result so far: 166550.68
Deduct 3928 from 4340 and we're left 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.

Step 11:
491 can be fit into 4120 8 times, resulting in a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 166550.688
If we subtract 3928 from 4120, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 166550.688 with a remainder of 0.0192.
