We look at the division of 88758245 by 609 
The aim is to understand the frequency of 609 in 88758245.

On to step 1:
If we divide 8 by 609, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 609

Let's proceed to step 2:
If we divide 88 by 609, we get 0 and a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Fetch the next digit (7) from the dividend, attach it to 88 and continue: 887 / 609

On to step 3:
The number 609 fits into 887 1 times, leaving a remainder of 278.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 609 from 887 and we're left with 278.
Fetch the next digit (5) from the dividend, attach it to 278 and continue: 2785 / 609

Step 4:
The number 609 fits into 2785 4 times, leaving a remainder of 349.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2436 from 2785 leaves us with 349.
Append the next digit (8) from the dividend to 349 and continue with: 3498 / 609

On to step 5:
3498 divided by 609 is 5 with a remainder of 453.
The next digit of our result is 5. 
Result so far: 145.0
Subtracting 3045 from 3498 leaves us with 453.
Append the next digit (2) from the dividend to 453 and continue with: 4532 / 609

Let's proceed to step 6:
609 goes into 4532 7 times with a remainder of 269.
The number 7 becomes the next digit in our result. 
Result so far: 1457.0
Deduct 4263 from 4532 and we're left with 269.
Append the next digit (4) from the dividend to 269 and continue with: 2694 / 609

Step 7:
If we divide 2694 by 609, we get 4 and a remainder of 258.
The next digit of our result is 4. 
Result so far: 14574.0
Subtracting 2436 from 2694 leaves us with 258.
Bring next digit (5) of the dividend behind the 258 and repeat the process: 2585 / 609

Going ahead to step 8:
The number 609 fits into 2585 4 times, leaving a remainder of 149.
Record the quotient 4 as the next digit in the result. 
Result so far: 145744.0
Subtract 2436 from 2585 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 9:
When dividing 1490 by 609, we get 2 with a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 145744.2
The remainder is 272 after subtracting 1218 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 10:
When dividing 2720 by 609, we get 4 with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 145744.24
The remainder is 284 after subtracting 2436 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 11:
When dividing 2840 by 609, we get 4 with a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 145744.244
If we subtract 2436 from 2840, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final outcome is 145744.244, with a leftover of 0.0404.
