81093336 divided by 338 
We want to figure out the number of times 81093336 can be divided by 338.

On to step 1:
If we divide 8 by 338, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 338

Step 2:
The number 338 fits into 81 0 times, leaving a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 338

Let's proceed to step 3:
338 can be fit into 810 2 times, resulting in a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 676 from 810 and we're left with 134.
Include the next digit (9) from the dividend after 134, then repeat: 1349 / 338

On to step 4:
The number 338 fits into 1349 3 times, leaving a remainder of 335.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 1014 from 1349 leaves us with 335.
Include the next digit (3) from the dividend after 335, then repeat: 3353 / 338

Step 5:
3353 divided by 338 is 9 with a remainder of 311.
Use 9 as the next digit of our solution. 
Result so far: 239.0
Subtract 3042 from 3353 to get 311.
Grab the next digit (3) from the dividend, add it to 311, then carry on: 3113 / 338

Going ahead to step 6:
If we divide 3113 by 338, we get 9 and a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 2399.0
If we take 3042 away from 3113, we end up with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 338

Going ahead to step 7:
If we divide 713 by 338, we get 2 and a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 23992.0
If we take 676 away from 713, we end up with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 338

Going ahead to step 8:
376 divided by 338 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 239921.0
Deduct 338 from 376 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 338 fits into 380 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 239921.1
Subtract 338 from 380 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
When dividing 420 by 338, we get 1 with a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 239921.11
The remainder is 82 after subtracting 338 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

After the division, we end up with 239921.11 and a remainder of 0.082.
