81353450 divided by 838 
We want to figure out the number of times 81353450 can be divided by 838.

Advancing to step 1:
If we divide 8 by 838, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 838

Let's proceed to step 2:
The number 838 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 838

On to step 3:
838 goes into 813 0 times with a remainder of 813.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 813 after subtracting 0 from 813.
Include the next digit (5) from the dividend after 813, then repeat: 8135 / 838

Advancing to step 4:
838 can be fit into 8135 9 times, resulting in a remainder of 593.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7542 from 8135 leaves us with 593.
Grab the next digit (3) from the dividend, add it to 593, then carry on: 5933 / 838

Let's proceed to step 5:
If we divide 5933 by 838, we get 7 and a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtract 5866 from 5933 to get 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 838

Step 6:
If we divide 674 by 838, we get 0 and a remainder of 674.
Use 0 as the next digit of our solution. 
Result so far: 970.0
The remainder is 674 after subtracting 0 from 674.
Append the next digit (5) from the dividend to 674 and continue with: 6745 / 838

Let's proceed to step 7:
If we divide 6745 by 838, we get 8 and a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 9708.0
If we take 6704 away from 6745, we end up with 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 838

Moving on to step 8:
The number 838 fits into 410 0 times, leaving a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 97080.0
Deduct 0 from 410 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 9:
4100 divided by 838 is 4 with a remainder of 748.
Put 4 as the next digit of the answer. 
Result so far: 97080.4
If we subtract 3352 from 4100, we get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Advancing to step 10:
838 goes into 7480 8 times with a remainder of 776.
Write down 8 as next digit of the result. 
Result so far: 97080.48
If we subtract 6704 from 7480, we get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Let's proceed to step 11:
7760 divided by 838 is 9 with a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 97080.489
Deduct 7542 from 7760 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 12:
If we divide 2180 by 838, we get 2 and a remainder of 504.
The number 2 becomes the next digit in our result. 
Result so far: 97080.4892
Subtract 1676 from 2180 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 13:
5040 divided by 838 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 97080.48926
Subtracting 5028 from 5040 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
The number 838 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 97080.48926
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
1200 divided by 838 is 1 with a remainder of 362.
Put 1 as the next digit of the answer. 
Result so far: 97080.4892601
Deduct 838 from 1200 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 16:
3620 divided by 838 is 4 with a remainder of 268.
The next digit of our result is 4. 
Result so far: 97080.48926014
Deduct 3352 from 3620 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final outcome is 97080.48926014, with a leftover of 2.68e-07.
