Let's divide 80164245 by 815
Let's see how many times 815 fits into 80164245.

Let's proceed to step 1:
When dividing 8 by 815, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 815

Moving on to step 2:
The number 815 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 815

Step 3:
801 divided by 815 is 0 with a remainder of 801.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 801 after subtracting 0 from 801.
Bring next digit (6) of the dividend behind the 801 and repeat the process: 8016 / 815

On to step 4:
815 can be fit into 8016 9 times, resulting in a remainder of 681.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 7335 away from 8016, we end up with 681.
Bring next digit (4) of the dividend behind the 681 and repeat the process: 6814 / 815

Going ahead to step 5:
815 goes into 6814 8 times with a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we take 6520 away from 6814, we end up with 294.
Grab the next digit (2) from the dividend, add it to 294, then carry on: 2942 / 815

On to step 6:
If we divide 2942 by 815, we get 3 and a remainder of 497.
Write down 3 as next digit of the result. 
Result so far: 983.0
Subtract 2445 from 2942 to get 497.
Bring next digit (4) of the dividend behind the 497 and repeat the process: 4974 / 815

Going ahead to step 7:
815 goes into 4974 6 times with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 9836.0
Subtracting 4890 from 4974 leaves us with 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 815

On to step 8:
845 divided by 815 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 98361.0
If we subtract 815 from 845, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
815 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 98361.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 10:
815 goes into 3000 3 times with a remainder of 555.
Record the quotient 3 as the next digit in the result. 
Result so far: 98361.03
Subtracting 2445 from 3000 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Let's proceed to step 11:
815 goes into 5550 6 times with a remainder of 660.
Put 6 as the next digit of the answer. 
Result so far: 98361.036
The remainder is 660 after subtracting 4890 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 12:
6600 divided by 815 is 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 98361.0368
If we subtract 6520 from 6600, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
800 divided by 815 is 0 with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 98361.0368
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 14:
8000 divided by 815 is 9 with a remainder of 665.
The next digit of our result is 9. 
Result so far: 98361.036809
The remainder is 665 after subtracting 7335 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Going ahead to step 15:
When dividing 6650 by 815, we get 8 with a remainder of 130.
Use 8 as the next digit of our solution. 
Result so far: 98361.0368098
If we take 6520 away from 6650, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
The number 815 fits into 1300 1 times, leaving a remainder of 485.
The number 1 becomes the next digit in our result. 
Result so far: 98361.03680981
Subtract 815 from 1300 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

The final outcome is 98361.03680981, with a leftover of 4.85e-07.
