Let's divide 81385457 by 818
Let's see how many times 818 fits into 81385457.

Going ahead to step 1:
818 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 818

Let's proceed to step 2:
When dividing 81 by 818, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 818

Moving on to step 3:
When dividing 813 by 818, we get 0 with a remainder of 813.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 813 and we're left with 813.
Bring next digit (8) of the dividend behind the 813 and repeat the process: 8138 / 818

Advancing to step 4:
818 can be fit into 8138 9 times, resulting in a remainder of 776.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 776 after subtracting 7362 from 8138.
Fetch the next digit (5) from the dividend, attach it to 776 and continue: 7765 / 818

Step 5:
818 goes into 7765 9 times with a remainder of 403.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 403 after subtracting 7362 from 7765.
Take the next digit (4) from the dividend and append it to 403, then repeat: 4034 / 818

On to step 6:
The number 818 fits into 4034 4 times, leaving a remainder of 762.
Write down 4 as next digit of the result. 
Result so far: 994.0
Deduct 3272 from 4034 and we're left with 762.
Include the next digit (5) from the dividend after 762, then repeat: 7625 / 818

Advancing to step 7:
818 can be fit into 7625 9 times, resulting in a remainder of 263.
Record the quotient 9 as the next digit in the result. 
Result so far: 9949.0
Deduct 7362 from 7625 and we're left with 263.
Grab the next digit (7) from the dividend, add it to 263, then carry on: 2637 / 818

Let's proceed to step 8:
When dividing 2637 by 818, we get 3 with a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 99493.0
If we subtract 2454 from 2637, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 9:
1830 divided by 818 is 2 with a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 99493.2
If we subtract 1636 from 1830, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
If we divide 1940 by 818, we get 2 and a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 99493.22
Subtracting 1636 from 1940 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Our division results in 99493.22 with a remaining 0.304.
