We look at the division of 81076930 by 516 
The aim is to understand the frequency of 516 in 81076930.

Step 1:
516 goes into 8 0 times with 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.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 516

Going ahead to step 2:
When dividing 81 by 516, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 516

Step 3:
If we divide 810 by 516, we get 1 and a remainder of 294.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 516 from 810 to get 294.
Bring next digit (7) of the dividend behind the 294 and repeat the process: 2947 / 516

Moving on to step 4:
2947 divided by 516 is 5 with a remainder of 367.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 2580 from 2947 to get 367.
Fetch the next digit (6) from the dividend, attach it to 367 and continue: 3676 / 516

Step 5:
3676 divided by 516 is 7 with a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 157.0
If we take 3612 away from 3676, we end up with 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 516

Moving on to step 6:
When dividing 649 by 516, we get 1 with a remainder of 133.
The next digit of our result is 1. 
Result so far: 1571.0
If we subtract 516 from 649, we get 133.
Fetch the next digit (3) from the dividend, attach it to 133 and continue: 1333 / 516

On to step 7:
When dividing 1333 by 516, we get 2 with a remainder of 301.
Use 2 as the next digit of our solution. 
Result so far: 15712.0
Deduct 1032 from 1333 and we're left with 301.
Include the next digit (0) from the dividend after 301, then repeat: 3010 / 516

Going ahead to step 8:
The number 516 fits into 3010 5 times, leaving a remainder of 430.
Record the quotient 5 as the next digit in the result. 
Result so far: 157125.0
The remainder is 430 after subtracting 2580 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 9:
516 can be fit into 4300 8 times, resulting in a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 157125.8
Subtract 4128 from 4300 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 10:
516 can be fit into 1720 3 times, resulting in a remainder of 172.
Use 3 as the next digit of our solution. 
Result so far: 157125.83
Deduct 1548 from 1720 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 11:
516 goes into 1720 3 times with a remainder of 172.
The number 3 becomes the next digit in our result. 
Result so far: 157125.833
Subtract 1548 from 1720 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 157125.833, with a leftover of 0.0172.
