12755334 ÷ 813 
We want to figure out the number of times 12755334 can be divided by 813.

Step 1:
If we divide 1 by 813, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 813

Going ahead to step 2:
813 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 813

Step 3:
813 can be fit into 127 0 times, resulting in a remainder of 127.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 127 to get 127.
Include the next digit (5) from the dividend after 127, then repeat: 1275 / 813

Let's proceed to step 4:
The number 813 fits into 1275 1 times, leaving a remainder of 462.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 462 after subtracting 813 from 1275.
Append the next digit (5) from the dividend to 462 and continue with: 4625 / 813

Let's proceed to step 5:
4625 divided by 813 is 5 with a remainder of 560.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 4065 from 4625, we get 560.
Fetch the next digit (3) from the dividend, attach it to 560 and continue: 5603 / 813

Moving on to step 6:
813 goes into 5603 6 times with a remainder of 725.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Deduct 4878 from 5603 and we're left with 725.
Append the next digit (3) from the dividend to 725 and continue with: 7253 / 813

On to step 7:
When dividing 7253 by 813, we get 8 with a remainder of 749.
Write down 8 as next digit of the result. 
Result so far: 1568.0
If we subtract 6504 from 7253, we get 749.
Bring next digit (4) of the dividend behind the 749 and repeat the process: 7494 / 813

Let's proceed to step 8:
813 can be fit into 7494 9 times, resulting in a remainder of 177.
Write down 9 as next digit of the result. 
Result so far: 15689.0
The remainder is 177 after subtracting 7317 from 7494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 9:
If we divide 1770 by 813, we get 2 and a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 15689.2
If we subtract 1626 from 1770, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 10:
813 goes into 1440 1 times with a remainder of 627.
Put 1 as the next digit of the answer. 
Result so far: 15689.21
Subtracting 813 from 1440 leaves us with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Step 11:
If we divide 6270 by 813, we get 7 and a remainder of 579.
The next digit of our result is 7. 
Result so far: 15689.217
If we subtract 5691 from 6270, we get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Moving on to step 12:
When dividing 5790 by 813, we get 7 with a remainder of 99.
Record the quotient 7 as the next digit in the result. 
Result so far: 15689.2177
If we subtract 5691 from 5790, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Our division results in 15689.2177 with a remaining 0.00099.
