81028784 divided by 500 
The aim is to understand the frequency of 500 in 81028784.

On to step 1:
500 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 500

Going ahead to step 2:
If we divide 81 by 500, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 500

Going ahead to step 3:
500 goes into 810 1 times with a remainder of 310.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 500 from 810 to get 310.
Take the next digit (2) from the dividend and append it to 310, then repeat: 3102 / 500

On to step 4:
The number 500 fits into 3102 6 times, leaving a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 3000 from 3102, we get 102.
Fetch the next digit (8) from the dividend, attach it to 102 and continue: 1028 / 500

Moving on to step 5:
500 can be fit into 1028 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
Subtracting 1000 from 1028 leaves us with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 500

Step 6:
When dividing 287 by 500, we get 0 with a remainder of 287.
The number 0 becomes the next digit in our result. 
Result so far: 1620.0
The remainder is 287 after subtracting 0 from 287.
Include the next digit (8) from the dividend after 287, then repeat: 2878 / 500

Step 7:
2878 divided by 500 is 5 with a remainder of 378.
Write down 5 as next digit of the result. 
Result so far: 16205.0
If we subtract 2500 from 2878, we get 378.
Include the next digit (4) from the dividend after 378, then repeat: 3784 / 500

On to step 8:
500 goes into 3784 7 times with a remainder of 284.
Use 7 as the next digit of our solution. 
Result so far: 162057.0
If we subtract 3500 from 3784, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 9:
2840 divided by 500 is 5 with a remainder of 340.
Record the quotient 5 as the next digit in the result. 
Result so far: 162057.5
The remainder is 340 after subtracting 2500 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 10:
The number 500 fits into 3400 6 times, leaving a remainder of 400.
Write down 6 as next digit of the result. 
Result so far: 162057.56
Subtracting 3000 from 3400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
The number 500 fits into 4000 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 162057.568
If we take 4000 away from 4000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
When dividing 0 by 500, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 162057.568
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
The number 500 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 162057.568
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 162057.568 with a remaining 0.0.
