We're dividing 16116716 by 509 
The aim is to understand the frequency of 509 in 16116716.

Moving on to step 1:
509 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 509

Advancing to step 2:
If we divide 16 by 509, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 509

Advancing to step 3:
When dividing 161 by 509, we get 0 with a remainder of 161.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 161 leaves us with 161.
Append the next digit (1) from the dividend to 161 and continue with: 1611 / 509

Advancing to step 4:
509 goes into 1611 3 times with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1527 from 1611 and we're left with 84.
Bring next digit (6) of the dividend behind the 84 and repeat the process: 846 / 509

Let's proceed to step 5:
The number 509 fits into 846 1 times, leaving a remainder of 337.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 509 from 846 leaves us with 337.
Include the next digit (7) from the dividend after 337, then repeat: 3377 / 509

Let's proceed to step 6:
If we divide 3377 by 509, we get 6 and a remainder of 323.
Write down 6 as next digit of the result. 
Result so far: 316.0
Subtracting 3054 from 3377 leaves us with 323.
Include the next digit (1) from the dividend after 323, then repeat: 3231 / 509

Step 7:
3231 divided by 509 is 6 with a remainder of 177.
Write down 6 as next digit of the result. 
Result so far: 3166.0
Deduct 3054 from 3231 and we're left with 177.
Fetch the next digit (6) from the dividend, attach it to 177 and continue: 1776 / 509

Let's proceed to step 8:
The number 509 fits into 1776 3 times, leaving a remainder of 249.
Write down 3 as next digit of the result. 
Result so far: 31663.0
Deduct 1527 from 1776 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 9:
The number 509 fits into 2490 4 times, leaving a remainder of 454.
Use 4 as the next digit of our solution. 
Result so far: 31663.4
Deduct 2036 from 2490 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 10:
509 goes into 4540 8 times with a remainder of 468.
Use 8 as the next digit of our solution. 
Result so far: 31663.48
The remainder is 468 after subtracting 4072 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 11:
The number 509 fits into 4680 9 times, leaving a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 31663.489
Subtract 4581 from 4680 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 12:
When dividing 990 by 509, we get 1 with a remainder of 481.
Put 1 as the next digit of the answer. 
Result so far: 31663.4891
The remainder is 481 after subtracting 509 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Advancing to step 13:
4810 divided by 509 is 9 with a remainder of 229.
Use 9 as the next digit of our solution. 
Result so far: 31663.48919
If we take 4581 away from 4810, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 14:
When dividing 2290 by 509, we get 4 with a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 31663.489194
Subtract 2036 from 2290 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 15:
When dividing 2540 by 509, we get 4 with a remainder of 504.
Write down 4 as next digit of the result. 
Result so far: 31663.4891944
The remainder is 504 after subtracting 2036 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

After the division, we end up with 31663.4891944 and a remainder of 5.04e-06.
