We look at the division of 88716641 by 864 
The aim is to understand the frequency of 864 in 88716641.

Let's proceed to step 1:
8 divided by 864 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 864

On to step 2:
88 divided by 864 is 0 with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Include the next digit (7) from the dividend after 88, then repeat: 887 / 864

Going ahead to step 3:
The number 864 fits into 887 1 times, leaving a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 864 away from 887, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 864

Advancing to step 4:
The number 864 fits into 231 0 times, leaving a remainder of 231.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 231 to get 231.
Bring next digit (6) of the dividend behind the 231 and repeat the process: 2316 / 864

Moving on to step 5:
2316 divided by 864 is 2 with a remainder of 588.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 588 after subtracting 1728 from 2316.
Fetch the next digit (6) from the dividend, attach it to 588 and continue: 5886 / 864

Let's proceed to step 6:
The number 864 fits into 5886 6 times, leaving a remainder of 702.
Put 6 as the next digit of the answer. 
Result so far: 1026.0
Deduct 5184 from 5886 and we're left with 702.
Grab the next digit (4) from the dividend, add it to 702, then carry on: 7024 / 864

Advancing to step 7:
7024 divided by 864 is 8 with a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 10268.0
The remainder is 112 after subtracting 6912 from 7024.
Take the next digit (1) from the dividend and append it to 112, then repeat: 1121 / 864

On to step 8:
864 can be fit into 1121 1 times, resulting in a remainder of 257.
Use 1 as the next digit of our solution. 
Result so far: 102681.0
Deduct 864 from 1121 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 9:
864 goes into 2570 2 times with a remainder of 842.
The next digit of our result is 2. 
Result so far: 102681.2
Deduct 1728 from 2570 and we're left with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Moving on to step 10:
When dividing 8420 by 864, we get 9 with a remainder of 644.
Record the quotient 9 as the next digit in the result. 
Result so far: 102681.29
Subtracting 7776 from 8420 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 11:
6440 divided by 864 is 7 with a remainder of 392.
The next digit of our result is 7. 
Result so far: 102681.297
Subtract 6048 from 6440 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 12:
864 goes into 3920 4 times with a remainder of 464.
The next digit of our result is 4. 
Result so far: 102681.2974
If we take 3456 away from 3920, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 13:
864 can be fit into 4640 5 times, resulting in a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 102681.29745
If we take 4320 away from 4640, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
3200 divided by 864 is 3 with a remainder of 608.
Use 3 as the next digit of our solution. 
Result so far: 102681.297453
If we take 2592 away from 3200, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 15:
The number 864 fits into 6080 7 times, leaving a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 102681.2974537
Deduct 6048 from 6080 and we're left 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.

Let's proceed to step 16:
The number 864 fits into 320 0 times, leaving a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 102681.2974537
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 102681.2974537 with a remainder of 3.2e-07.
