81648097 divided by 391 
We're looking to find how many times 391 goes into 81648097.

Advancing to step 1:
When dividing 8 by 391, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 391

Step 2:
81 divided by 391 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 391

Step 3:
When dividing 816 by 391, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 782 from 816, we get 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 391

Going ahead to step 4:
The number 391 fits into 344 0 times, leaving a remainder of 344.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 344 and we're left with 344.
Grab the next digit (8) from the dividend, add it to 344, then carry on: 3448 / 391

Moving on to step 5:
391 can be fit into 3448 8 times, resulting in a remainder of 320.
The next digit of our result is 8. 
Result so far: 208.0
If we subtract 3128 from 3448, we get 320.
Grab the next digit (0) from the dividend, add it to 320, then carry on: 3200 / 391

Step 6:
The number 391 fits into 3200 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 2088.0
The remainder is 72 after subtracting 3128 from 3200.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 391

Going ahead to step 7:
391 goes into 729 1 times with a remainder of 338.
Write down 1 as next digit of the result. 
Result so far: 20881.0
Subtracting 391 from 729 leaves us with 338.
Fetch the next digit (7) from the dividend, attach it to 338 and continue: 3387 / 391

Step 8:
391 can be fit into 3387 8 times, resulting in a remainder of 259.
Record the quotient 8 as the next digit in the result. 
Result so far: 208818.0
The remainder is 259 after subtracting 3128 from 3387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 9:
When dividing 2590 by 391, we get 6 with a remainder of 244.
The number 6 becomes the next digit in our result. 
Result so far: 208818.6
Deduct 2346 from 2590 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 10:
The number 391 fits into 2440 6 times, leaving a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 208818.66
If we take 2346 away from 2440, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 208818.66 with a remainder of 0.094.
