398509 divided by 88 
The aim is to understand the frequency of 88 in 398509.

Moving on to step 1:
3 divided by 88 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 88

Step 2:
If we divide 39 by 88, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 88

Step 3:
The number 88 fits into 398 4 times, leaving a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 352 from 398 to get 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 88

Step 4:
The number 88 fits into 465 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 440 away from 465, we end up with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 88

On to step 5:
When dividing 250 by 88, we get 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 452.0
If we subtract 176 from 250, we get 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 88

Moving on to step 6:
When dividing 749 by 88, we get 8 with a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 4528.0
Subtract 704 from 749 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
When dividing 450 by 88, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 4528.5
If we take 440 away from 450, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
88 goes into 100 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 4528.51
If we take 88 away from 100, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
88 can be fit into 120 1 times, resulting in a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 4528.511
Subtracting 88 from 120 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 4528.511 with a balance of 0.0032.
