27527449 divided by 509 
The aim is to understand the frequency of 509 in 27527449.

Advancing to step 1:
509 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 509

Let's proceed to step 2:
When dividing 27 by 509, we get 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 509

On to step 3:
509 can be fit into 275 0 times, resulting in a remainder of 275.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 275 and we're left with 275.
Bring next digit (2) of the dividend behind the 275 and repeat the process: 2752 / 509

Going ahead to step 4:
509 goes into 2752 5 times with a remainder of 207.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 2545 from 2752 to get 207.
Grab the next digit (7) from the dividend, add it to 207, then carry on: 2077 / 509

Moving on to step 5:
509 can be fit into 2077 4 times, resulting in a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtract 2036 from 2077 to get 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 509

Let's proceed to step 6:
If we divide 414 by 509, we get 0 and a remainder of 414.
Put 0 as the next digit of the answer. 
Result so far: 540.0
If we subtract 0 from 414, we get 414.
Grab the next digit (4) from the dividend, add it to 414, then carry on: 4144 / 509

Advancing to step 7:
If we divide 4144 by 509, we get 8 and a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 5408.0
The remainder is 72 after subtracting 4072 from 4144.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 509

Advancing to step 8:
509 can be fit into 729 1 times, resulting in a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 54081.0
If we take 509 away from 729, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 9:
The number 509 fits into 2200 4 times, leaving a remainder of 164.
Put 4 as the next digit of the answer. 
Result so far: 54081.4
The remainder is 164 after subtracting 2036 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 10:
When dividing 1640 by 509, we get 3 with a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 54081.43
If we take 1527 away from 1640, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 11:
509 can be fit into 1130 2 times, resulting in a remainder of 112.
The next digit of our result is 2. 
Result so far: 54081.432
Deduct 1018 from 1130 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
509 can be fit into 1120 2 times, resulting in a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 54081.4322
Deduct 1018 from 1120 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Our division results in 54081.4322 with a remaining 0.00102.
