Let's divide 91001310 by 815
We want to figure out the number of times 91001310 can be divided by 815.

Moving on to step 1:
9 divided by 815 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 815

Advancing to step 2:
When dividing 91 by 815, we get 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 815

Let's proceed to step 3:
When dividing 910 by 815, we get 1 with a remainder of 95.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 815 from 910, we get 95.
Bring next digit (0) of the dividend behind the 95 and repeat the process: 950 / 815

Let's proceed to step 4:
When dividing 950 by 815, we get 1 with a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 815 from 950 to get 135.
Append the next digit (1) from the dividend to 135 and continue with: 1351 / 815

On to step 5:
If we divide 1351 by 815, we get 1 and a remainder of 536.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
The remainder is 536 after subtracting 815 from 1351.
Bring next digit (3) of the dividend behind the 536 and repeat the process: 5363 / 815

Going ahead to step 6:
The number 815 fits into 5363 6 times, leaving a remainder of 473.
Record the quotient 6 as the next digit in the result. 
Result so far: 1116.0
The remainder is 473 after subtracting 4890 from 5363.
Include the next digit (1) from the dividend after 473, then repeat: 4731 / 815

Let's proceed to step 7:
The number 815 fits into 4731 5 times, leaving a remainder of 656.
Use 5 as the next digit of our solution. 
Result so far: 11165.0
If we subtract 4075 from 4731, we get 656.
Take the next digit (0) from the dividend and append it to 656, then repeat: 6560 / 815

Going ahead to step 8:
If we divide 6560 by 815, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 111658.0
If we take 6520 away from 6560, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
815 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 111658.0
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 10:
The number 815 fits into 4000 4 times, leaving a remainder of 740.
Use 4 as the next digit of our solution. 
Result so far: 111658.04
Subtracting 3260 from 4000 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 11:
7400 divided by 815 is 9 with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 111658.049
If we subtract 7335 from 7400, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 12:
815 goes into 650 0 times with a remainder of 650.
The next digit of our result is 0. 
Result so far: 111658.049
The remainder is 650 after subtracting 0 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 13:
815 goes into 6500 7 times with a remainder of 795.
Write down 7 as next digit of the result. 
Result so far: 111658.04907
Subtracting 5705 from 6500 leaves us with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Step 14:
The number 815 fits into 7950 9 times, leaving a remainder of 615.
Write down 9 as next digit of the result. 
Result so far: 111658.049079
Deduct 7335 from 7950 and we're left with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 15:
815 goes into 6150 7 times with a remainder of 445.
The next digit of our result is 7. 
Result so far: 111658.0490797
Deduct 5705 from 6150 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 16:
4450 divided by 815 is 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 111658.04907975
Subtracting 4075 from 4450 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

In conclusion, the division gives 111658.04907975 with a balance of 3.75e-07.
