We look at the division of 52727769 by 609 
The aim is to understand the frequency of 609 in 52727769.

Step 1:
609 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 609

Advancing to step 2:
When dividing 52 by 609, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 609

Going ahead to step 3:
609 can be fit into 527 0 times, resulting in a remainder of 527.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 527, we end up with 527.
Take the next digit (2) from the dividend and append it to 527, then repeat: 5272 / 609

Let's proceed to step 4:
If we divide 5272 by 609, we get 8 and a remainder of 400.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 4872 away from 5272, we end up with 400.
Take the next digit (7) from the dividend and append it to 400, then repeat: 4007 / 609

Moving on to step 5:
When dividing 4007 by 609, we get 6 with a remainder of 353.
Write down 6 as next digit of the result. 
Result so far: 86.0
If we take 3654 away from 4007, we end up with 353.
Append the next digit (7) from the dividend to 353 and continue with: 3537 / 609

Let's proceed to step 6:
The number 609 fits into 3537 5 times, leaving a remainder of 492.
Use 5 as the next digit of our solution. 
Result so far: 865.0
If we take 3045 away from 3537, we end up with 492.
Bring next digit (6) of the dividend behind the 492 and repeat the process: 4926 / 609

Step 7:
The number 609 fits into 4926 8 times, leaving a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 8658.0
Deduct 4872 from 4926 and we're left with 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 609

Advancing to step 8:
When dividing 549 by 609, we get 0 with a remainder of 549.
Write down 0 as next digit of the result. 
Result so far: 86580.0
The remainder is 549 after subtracting 0 from 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Advancing to step 9:
If we divide 5490 by 609, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 86580.9
If we subtract 5481 from 5490, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
609 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 86580.9
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 11:
When dividing 900 by 609, we get 1 with a remainder of 291.
The next digit of our result is 1. 
Result so far: 86580.901
Subtract 609 from 900 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 12:
The number 609 fits into 2910 4 times, leaving a remainder of 474.
The next digit of our result is 4. 
Result so far: 86580.9014
Deduct 2436 from 2910 and we're left with 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 13:
If we divide 4740 by 609, we get 7 and a remainder of 477.
Record the quotient 7 as the next digit in the result. 
Result so far: 86580.90147
If we subtract 4263 from 4740, we get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Let's proceed to step 14:
If we divide 4770 by 609, we get 7 and a remainder of 507.
Write down 7 as next digit of the result. 
Result so far: 86580.901477
Subtracting 4263 from 4770 leaves us with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

The final outcome is 86580.901477, with a leftover of 5.07e-05.
