81812712 divided by 658 
We want to figure out the number of times 81812712 can be divided by 658.

Going ahead to step 1:
When dividing 8 by 658, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 658

Moving on to step 2:
When dividing 81 by 658, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 658

Moving on to step 3:
If we divide 818 by 658, we get 1 and a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 658 from 818 leaves us with 160.
Take the next digit (1) from the dividend and append it to 160, then repeat: 1601 / 658

Moving on to step 4:
If we divide 1601 by 658, we get 2 and a remainder of 285.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1316 from 1601 and we're left with 285.
Take the next digit (2) from the dividend and append it to 285, then repeat: 2852 / 658

Moving on to step 5:
658 can be fit into 2852 4 times, resulting in a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Deduct 2632 from 2852 and we're left with 220.
Fetch the next digit (7) from the dividend, attach it to 220 and continue: 2207 / 658

Moving on to step 6:
658 goes into 2207 3 times with a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 1243.0
If we take 1974 away from 2207, we end up with 233.
Bring next digit (1) of the dividend behind the 233 and repeat the process: 2331 / 658

Step 7:
The number 658 fits into 2331 3 times, leaving a remainder of 357.
Use 3 as the next digit of our solution. 
Result so far: 12433.0
Subtract 1974 from 2331 to get 357.
Append the next digit (2) from the dividend to 357 and continue with: 3572 / 658

Step 8:
When dividing 3572 by 658, we get 5 with a remainder of 282.
Put 5 as the next digit of the answer. 
Result so far: 124335.0
If we take 3290 away from 3572, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 9:
658 goes into 2820 4 times with a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 124335.4
If we subtract 2632 from 2820, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
658 can be fit into 1880 2 times, resulting in a remainder of 564.
The number 2 becomes the next digit in our result. 
Result so far: 124335.42
Deduct 1316 from 1880 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 11:
If we divide 5640 by 658, we get 8 and a remainder of 376.
The next digit of our result is 8. 
Result so far: 124335.428
The remainder is 376 after subtracting 5264 from 5640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 12:
658 can be fit into 3760 5 times, resulting in a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 124335.4285
If we take 3290 away from 3760, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 13:
658 goes into 4700 7 times with a remainder of 94.
The next digit of our result is 7. 
Result so far: 124335.42857
If we take 4606 away from 4700, 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.

Let's proceed to step 14:
940 divided by 658 is 1 with a remainder of 282.
Record the quotient 1 as the next digit in the result. 
Result so far: 124335.428571
Subtract 658 from 940 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 15:
2820 divided by 658 is 4 with a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 124335.4285714
If we subtract 2632 from 2820, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 16:
When dividing 1880 by 658, we get 2 with a remainder of 564.
The next digit of our result is 2. 
Result so far: 124335.42857142
Subtract 1316 from 1880 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

In conclusion, the division gives 124335.42857142 with a balance of 5.64e-07.
