We look at the division of 88387613 by 864 
The aim is to understand the frequency of 864 in 88387613.

Let's proceed to step 1:
864 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 864

Going ahead to step 2:
The number 864 fits into 88 0 times, leaving a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Include the next digit (3) from the dividend after 88, then repeat: 883 / 864

On to step 3:
864 goes into 883 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 864 from 883 and we're left with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 864

On to step 4:
If we divide 198 by 864, we get 0 and a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 198 and we're left with 198.
Grab the next digit (7) from the dividend, add it to 198, then carry on: 1987 / 864

Step 5:
864 can be fit into 1987 2 times, resulting in a remainder of 259.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Deduct 1728 from 1987 and we're left with 259.
Grab the next digit (6) from the dividend, add it to 259, then carry on: 2596 / 864

On to step 6:
864 can be fit into 2596 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 1023.0
If we take 2592 away from 2596, we end up with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 864

Let's proceed to step 7:
41 divided by 864 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 10230.0
Subtracting 0 from 41 leaves us with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 864

On to step 8:
When dividing 413 by 864, we get 0 with a remainder of 413.
The number 0 becomes the next digit in our result. 
Result so far: 102300.0
If we subtract 0 from 413, we get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

On to step 9:
If we divide 4130 by 864, we get 4 and a remainder of 674.
The next digit of our result is 4. 
Result so far: 102300.4
Subtracting 3456 from 4130 leaves us with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Moving on to step 10:
864 can be fit into 6740 7 times, resulting in a remainder of 692.
The next digit of our result is 7. 
Result so far: 102300.47
If we take 6048 away from 6740, we end up with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Going ahead to step 11:
6920 divided by 864 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 102300.478
If we subtract 6912 from 6920, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
The number 864 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 102300.478
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
When dividing 800 by 864, we get 0 with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 102300.478
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

In conclusion, the division gives 102300.478 with a balance of 0.0008.
