We divide 81389982 by 815
Our goal is to divide 81389982 by 815.

On to step 1:
815 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 815

Step 2:
815 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 815

Moving on to step 3:
The number 815 fits into 813 0 times, leaving a remainder of 813.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 813 after subtracting 0 from 813.
Append the next digit (8) from the dividend to 813 and continue with: 8138 / 815

Step 4:
815 can be fit into 8138 9 times, resulting in a remainder of 803.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7335 from 8138, we get 803.
Include the next digit (9) from the dividend after 803, then repeat: 8039 / 815

Step 5:
815 can be fit into 8039 9 times, resulting in a remainder of 704.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 704 after subtracting 7335 from 8039.
Fetch the next digit (9) from the dividend, attach it to 704 and continue: 7049 / 815

On to step 6:
815 goes into 7049 8 times with a remainder of 529.
The number 8 becomes the next digit in our result. 
Result so far: 998.0
If we subtract 6520 from 7049, we get 529.
Take the next digit (8) from the dividend and append it to 529, then repeat: 5298 / 815

On to step 7:
815 can be fit into 5298 6 times, resulting in a remainder of 408.
The next digit of our result is 6. 
Result so far: 9986.0
Subtract 4890 from 5298 to get 408.
Fetch the next digit (2) from the dividend, attach it to 408 and continue: 4082 / 815

On to step 8:
When dividing 4082 by 815, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 99865.0
Subtract 4075 from 4082 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
The number 815 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 99865.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
When dividing 700 by 815, we get 0 with a remainder of 700.
The next digit of our result is 0. 
Result so far: 99865.0
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final result is 99865.0 with a remainder of 0.7.
