96771945 divided by 509 
The aim is to understand the frequency of 509 in 96771945.

Going ahead to step 1:
509 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 509

On to step 2:
When dividing 96 by 509, we get 0 with a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 96, we end up with 96.
Fetch the next digit (7) from the dividend, attach it to 96 and continue: 967 / 509

Moving on to step 3:
509 can be fit into 967 1 times, resulting in a remainder of 458.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 509 away from 967, we end up with 458.
Append the next digit (7) from the dividend to 458 and continue with: 4587 / 509

Advancing to step 4:
509 can be fit into 4587 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 4581 away from 4587, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 509

Moving on to step 5:
509 can be fit into 61 0 times, resulting in a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
If we subtract 0 from 61, we get 61.
Fetch the next digit (9) from the dividend, attach it to 61 and continue: 619 / 509

Step 6:
If we divide 619 by 509, we get 1 and a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 1901.0
Subtract 509 from 619 to get 110.
Take the next digit (4) from the dividend and append it to 110, then repeat: 1104 / 509

Let's proceed to step 7:
509 goes into 1104 2 times with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 19012.0
Subtract 1018 from 1104 to get 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 509

Moving on to step 8:
If we divide 865 by 509, we get 1 and a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 190121.0
Deduct 509 from 865 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 9:
509 can be fit into 3560 6 times, resulting in a remainder of 506.
Write down 6 as next digit of the result. 
Result so far: 190121.6
If we take 3054 away from 3560, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 10:
When dividing 5060 by 509, we get 9 with a remainder of 479.
Record the quotient 9 as the next digit in the result. 
Result so far: 190121.69
If we subtract 4581 from 5060, we get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Advancing to step 11:
4790 divided by 509 is 9 with a remainder of 209.
Record the quotient 9 as the next digit in the result. 
Result so far: 190121.699
If we subtract 4581 from 4790, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

The final result is 190121.699 with a remainder of 0.0209.
