We look at the division of 81321337 by 105 
We want to divide 81321337 by 105.

On to step 1:
105 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 105

On to step 2:
When dividing 81 by 105, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 105

On to step 3:
If we divide 813 by 105, we get 7 and a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 735 from 813 and we're left with 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 105

Advancing to step 4:
If we divide 782 by 105, we get 7 and a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtracting 735 from 782 leaves us with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 105

Going ahead to step 5:
105 goes into 471 4 times with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 774.0
Subtracting 420 from 471 leaves us with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 105

Moving on to step 6:
105 can be fit into 513 4 times, resulting in a remainder of 93.
Record the quotient 4 as the next digit in the result. 
Result so far: 7744.0
Deduct 420 from 513 and we're left with 93.
Append the next digit (3) from the dividend to 93 and continue with: 933 / 105

Moving on to step 7:
The number 105 fits into 933 8 times, leaving a remainder of 93.
The number 8 becomes the next digit in our result. 
Result so far: 77448.0
Subtract 840 from 933 to get 93.
Grab the next digit (7) from the dividend, add it to 93, then carry on: 937 / 105

On to step 8:
The number 105 fits into 937 8 times, leaving a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 774488.0
If we subtract 840 from 937, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
970 divided by 105 is 9 with a remainder of 25.
The next digit of our result is 9. 
Result so far: 774488.9
If we take 945 away from 970, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
105 goes into 250 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 774488.92
The remainder is 40 after subtracting 210 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
105 goes into 400 3 times with a remainder of 85.
The next digit of our result is 3. 
Result so far: 774488.923
Deduct 315 from 400 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 12:
850 divided by 105 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 774488.9238
Subtracting 840 from 850 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
105 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 774488.9238
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
If we divide 1000 by 105, we get 9 and a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 774488.923809
The remainder is 55 after subtracting 945 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 15:
105 can be fit into 550 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 774488.9238095
Subtracting 525 from 550 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 16:
105 can be fit into 250 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 774488.92380952
Subtracting 210 from 250 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 774488.92380952 with a remaining 4e-08.
