We look at the division of 81281168 by 504 
We want to figure out the number of times 81281168 can be divided by 504.

Going ahead to step 1:
The number 504 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 504

Let's proceed to step 2:
The number 504 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 504

Step 3:
If we divide 812 by 504, we get 1 and a remainder of 308.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 504 from 812 to get 308.
Include the next digit (8) from the dividend after 308, then repeat: 3088 / 504

On to step 4:
504 can be fit into 3088 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 3024 from 3088, we get 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 504

Let's proceed to step 5:
641 divided by 504 is 1 with a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we take 504 away from 641, we end up with 137.
Take the next digit (1) from the dividend and append it to 137, then repeat: 1371 / 504

Advancing to step 6:
504 goes into 1371 2 times with a remainder of 363.
The number 2 becomes the next digit in our result. 
Result so far: 1612.0
If we subtract 1008 from 1371, we get 363.
Fetch the next digit (6) from the dividend, attach it to 363 and continue: 3636 / 504

Going ahead to step 7:
504 can be fit into 3636 7 times, resulting in a remainder of 108.
Use 7 as the next digit of our solution. 
Result so far: 16127.0
If we subtract 3528 from 3636, we get 108.
Take the next digit (8) from the dividend and append it to 108, then repeat: 1088 / 504

Going ahead to step 8:
If we divide 1088 by 504, we get 2 and a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 161272.0
If we subtract 1008 from 1088, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
If we divide 800 by 504, we get 1 and a remainder of 296.
Put 1 as the next digit of the answer. 
Result so far: 161272.1
Subtract 504 from 800 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
If we divide 2960 by 504, we get 5 and a remainder of 440.
Use 5 as the next digit of our solution. 
Result so far: 161272.15
If we take 2520 away from 2960, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
If we divide 4400 by 504, we get 8 and a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 161272.158
Deduct 4032 from 4400 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 12:
3680 divided by 504 is 7 with a remainder of 152.
Put 7 as the next digit of the answer. 
Result so far: 161272.1587
If we subtract 3528 from 3680, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 13:
When dividing 1520 by 504, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 161272.15873
If we take 1512 away from 1520, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
When dividing 80 by 504, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 161272.15873
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
When dividing 800 by 504, we get 1 with a remainder of 296.
Record the quotient 1 as the next digit in the result. 
Result so far: 161272.1587301
Subtract 504 from 800 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 16:
If we divide 2960 by 504, we get 5 and a remainder of 440.
The next digit of our result is 5. 
Result so far: 161272.15873015
If we take 2520 away from 2960, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 161272.15873015, with a leftover of 4.4e-07.
