We divide 99913927 by 813
We want to divide 99913927 by 813.

Going ahead to step 1:
The number 813 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 813

Step 2:
If we divide 99 by 813, we get 0 and a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (9) from the dividend after 99, then repeat: 999 / 813

On to step 3:
813 goes into 999 1 times with a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 186 after subtracting 813 from 999.
Include the next digit (1) from the dividend after 186, then repeat: 1861 / 813

Let's proceed to step 4:
1861 divided by 813 is 2 with a remainder of 235.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1626 from 1861 and we're left with 235.
Fetch the next digit (3) from the dividend, attach it to 235 and continue: 2353 / 813

On to step 5:
2353 divided by 813 is 2 with a remainder of 727.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Subtract 1626 from 2353 to get 727.
Append the next digit (9) from the dividend to 727 and continue with: 7279 / 813

Step 6:
The number 813 fits into 7279 8 times, leaving a remainder of 775.
The number 8 becomes the next digit in our result. 
Result so far: 1228.0
Subtracting 6504 from 7279 leaves us with 775.
Append the next digit (2) from the dividend to 775 and continue with: 7752 / 813

Let's proceed to step 7:
813 goes into 7752 9 times with a remainder of 435.
Record the quotient 9 as the next digit in the result. 
Result so far: 12289.0
The remainder is 435 after subtracting 7317 from 7752.
Take the next digit (7) from the dividend and append it to 435, then repeat: 4357 / 813

Let's proceed to step 8:
If we divide 4357 by 813, we get 5 and a remainder of 292.
Put 5 as the next digit of the answer. 
Result so far: 122895.0
If we subtract 4065 from 4357, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 9:
813 goes into 2920 3 times with a remainder of 481.
The number 3 becomes the next digit in our result. 
Result so far: 122895.3
Subtracting 2439 from 2920 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Step 10:
If we divide 4810 by 813, we get 5 and a remainder of 745.
Record the quotient 5 as the next digit in the result. 
Result so far: 122895.35
Subtract 4065 from 4810 to get 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Going ahead to step 11:
813 can be fit into 7450 9 times, resulting in a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 122895.359
If we subtract 7317 from 7450, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 12:
The number 813 fits into 1330 1 times, leaving a remainder of 517.
Write down 1 as next digit of the result. 
Result so far: 122895.3591
Subtracting 813 from 1330 leaves us with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Let's proceed to step 13:
5170 divided by 813 is 6 with a remainder of 292.
The next digit of our result is 6. 
Result so far: 122895.35916
Subtracting 4878 from 5170 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 14:
813 goes into 2920 3 times with a remainder of 481.
The next digit of our result is 3. 
Result so far: 122895.359163
If we subtract 2439 from 2920, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Advancing to step 15:
The number 813 fits into 4810 5 times, leaving a remainder of 745.
Use 5 as the next digit of our solution. 
Result so far: 122895.3591635
Deduct 4065 from 4810 and we're left with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Moving on to step 16:
7450 divided by 813 is 9 with a remainder of 133.
The next digit of our result is 9. 
Result so far: 122895.35916359
Subtracting 7317 from 7450 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Our division results in 122895.35916359 with a remaining 1.33e-07.
