11305485 ÷ 813 
We want to divide 11305485 by 813.

Advancing to step 1:
813 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 813

Moving on to step 2:
The number 813 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 813

Moving on to step 3:
813 can be fit into 113 0 times, resulting in a remainder of 113.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 113 leaves us with 113.
Grab the next digit (0) from the dividend, add it to 113, then carry on: 1130 / 813

Moving on to step 4:
If we divide 1130 by 813, we get 1 and a remainder of 317.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 813 from 1130 to get 317.
Append the next digit (5) from the dividend to 317 and continue with: 3175 / 813

Step 5:
813 goes into 3175 3 times with a remainder of 736.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 2439 from 3175 to get 736.
Append the next digit (4) from the dividend to 736 and continue with: 7364 / 813

Moving on to step 6:
7364 divided by 813 is 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtract 7317 from 7364 to get 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 813

Moving on to step 7:
813 can be fit into 478 0 times, resulting in a remainder of 478.
The next digit of our result is 0. 
Result so far: 1390.0
Deduct 0 from 478 and we're left with 478.
Bring next digit (5) of the dividend behind the 478 and repeat the process: 4785 / 813

Let's proceed to step 8:
813 can be fit into 4785 5 times, resulting in a remainder of 720.
Write down 5 as next digit of the result. 
Result so far: 13905.0
If we take 4065 away from 4785, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 9:
If we divide 7200 by 813, we get 8 and a remainder of 696.
Record the quotient 8 as the next digit in the result. 
Result so far: 13905.8
The remainder is 696 after subtracting 6504 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Going ahead to step 10:
When dividing 6960 by 813, we get 8 with a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 13905.88
The remainder is 456 after subtracting 6504 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final outcome is 13905.88, with a leftover of 0.456.
