Let's divide 909375 by 88
The aim is to understand the frequency of 88 in 909375.

Step 1:
The number 88 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 88

On to step 2:
The number 88 fits into 90 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 88 away from 90, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 88

On to step 3:
If we divide 29 by 88, we get 0 and a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 88

Going ahead to step 4:
When dividing 293 by 88, we get 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 264 away from 293, we end up with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 88

Step 5:
If we divide 297 by 88, we get 3 and a remainder of 33.
The next digit of our result is 3. 
Result so far: 1033.0
Deduct 264 from 297 and we're left with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 88

Step 6:
When dividing 335 by 88, we get 3 with a remainder of 71.
The next digit of our result is 3. 
Result so far: 10333.0
If we subtract 264 from 335, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
88 can be fit into 710 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 10333.8
If we take 704 away from 710, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
88 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10333.8
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
88 goes into 600 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 10333.806
Subtract 528 from 600 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
88 can be fit into 720 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 10333.8068
The remainder is 16 after subtracting 704 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 88, we get 1 with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 10333.80681
If we subtract 88 from 160, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
88 goes into 720 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 10333.806818
Subtract 704 from 720 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 88, we get 1 and a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 10333.8068181
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
If we divide 720 by 88, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 10333.80681818
If we subtract 704 from 720, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 10333.80681818 with a remaining 1.6e-08.
