We're dividing 96899313 by 509 
The aim is to understand the frequency of 509 in 96899313.

Step 1:
509 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 509

Step 2:
509 can be fit into 96 0 times, resulting in a remainder of 96.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 96 to get 96.
Take the next digit (8) from the dividend and append it to 96, then repeat: 968 / 509

Moving on to step 3:
509 can be fit into 968 1 times, resulting in a remainder of 459.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 509 from 968, we get 459.
Take the next digit (9) from the dividend and append it to 459, then repeat: 4599 / 509

Step 4:
The number 509 fits into 4599 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 18 after subtracting 4581 from 4599.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 509

Step 5:
509 can be fit into 189 0 times, resulting in a remainder of 189.
Write down 0 as next digit of the result. 
Result so far: 190.0
If we take 0 away from 189, we end up with 189.
Bring next digit (3) of the dividend behind the 189 and repeat the process: 1893 / 509

Let's proceed to step 6:
509 can be fit into 1893 3 times, resulting in a remainder of 366.
Write down 3 as next digit of the result. 
Result so far: 1903.0
If we subtract 1527 from 1893, we get 366.
Take the next digit (1) from the dividend and append it to 366, then repeat: 3661 / 509

On to step 7:
509 goes into 3661 7 times with a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 19037.0
The remainder is 98 after subtracting 3563 from 3661.
Take the next digit (3) from the dividend and append it to 98, then repeat: 983 / 509

On to step 8:
If we divide 983 by 509, we get 1 and a remainder of 474.
The next digit of our result is 1. 
Result so far: 190371.0
Subtract 509 from 983 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 9:
If we divide 4740 by 509, we get 9 and a remainder of 159.
Write down 9 as next digit of the result. 
Result so far: 190371.9
The remainder is 159 after subtracting 4581 from 4740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 10:
1590 divided by 509 is 3 with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 190371.93
Subtract 1527 from 1590 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 11:
630 divided by 509 is 1 with a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 190371.931
The remainder is 121 after subtracting 509 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 12:
If we divide 1210 by 509, we get 2 and a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 190371.9312
Deduct 1018 from 1210 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 13:
1920 divided by 509 is 3 with a remainder of 393.
The next digit of our result is 3. 
Result so far: 190371.93123
Deduct 1527 from 1920 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 14:
509 can be fit into 3930 7 times, resulting in a remainder of 367.
Use 7 as the next digit of our solution. 
Result so far: 190371.931237
If we subtract 3563 from 3930, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 15:
The number 509 fits into 3670 7 times, leaving a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 190371.9312377
The remainder is 107 after subtracting 3563 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final result is 190371.9312377 with a remainder of 1.07e-06.
