Let's divide 515405 by 88
The aim is to understand the frequency of 88 in 515405.

Step 1:
The number 88 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 88

Let's proceed to step 2:
If we divide 51 by 88, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 88

Step 3:
If we divide 515 by 88, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 440 from 515 to get 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 88

Going ahead to step 4:
When dividing 754 by 88, we get 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we take 704 away from 754, we end up with 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 88

Moving on to step 5:
88 goes into 500 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 585.0
Deduct 440 from 500 and we're left with 60.
Take the next digit (5) from the dividend and append it to 60, then repeat: 605 / 88

On to step 6:
605 divided by 88 is 6 with a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 5856.0
The remainder is 77 after subtracting 528 from 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
If we divide 770 by 88, we get 8 and a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 5856.8
The remainder is 66 after subtracting 704 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
The number 88 fits into 660 7 times, leaving a remainder of 44.
The next digit of our result is 7. 
Result so far: 5856.87
The remainder is 44 after subtracting 616 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
88 can be fit into 440 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5856.875
The remainder is 0 after subtracting 440 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 88, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5856.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
88 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5856.875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5856.875 with a remaining 0.0.
