We look at the division of 76885696 by 865 
The aim is to understand the frequency of 865 in 76885696.

Going ahead to step 1:
7 divided by 865 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 865

On to step 2:
865 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 865

Going ahead to step 3:
If we divide 768 by 865, we get 0 and a remainder of 768.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 768 after subtracting 0 from 768.
Take the next digit (8) from the dividend and append it to 768, then repeat: 7688 / 865

Advancing to step 4:
7688 divided by 865 is 8 with a remainder of 768.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 768 after subtracting 6920 from 7688.
Bring next digit (5) of the dividend behind the 768 and repeat the process: 7685 / 865

Going ahead to step 5:
865 can be fit into 7685 8 times, resulting in a remainder of 765.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtract 6920 from 7685 to get 765.
Include the next digit (6) from the dividend after 765, then repeat: 7656 / 865

Moving on to step 6:
The number 865 fits into 7656 8 times, leaving a remainder of 736.
The number 8 becomes the next digit in our result. 
Result so far: 888.0
Subtracting 6920 from 7656 leaves us with 736.
Append the next digit (9) from the dividend to 736 and continue with: 7369 / 865

Advancing to step 7:
If we divide 7369 by 865, we get 8 and a remainder of 449.
The next digit of our result is 8. 
Result so far: 8888.0
If we take 6920 away from 7369, we end up with 449.
Bring next digit (6) of the dividend behind the 449 and repeat the process: 4496 / 865

Going ahead to step 8:
865 can be fit into 4496 5 times, resulting in a remainder of 171.
Put 5 as the next digit of the answer. 
Result so far: 88885.0
If we take 4325 away from 4496, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 9:
When dividing 1710 by 865, we get 1 with a remainder of 845.
The number 1 becomes the next digit in our result. 
Result so far: 88885.1
Subtract 865 from 1710 to get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

On to step 10:
8450 divided by 865 is 9 with a remainder of 665.
The number 9 becomes the next digit in our result. 
Result so far: 88885.19
The remainder is 665 after subtracting 7785 from 8450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Advancing to step 11:
6650 divided by 865 is 7 with a remainder of 595.
Record the quotient 7 as the next digit in the result. 
Result so far: 88885.197
If we take 6055 away from 6650, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 12:
5950 divided by 865 is 6 with a remainder of 760.
Put 6 as the next digit of the answer. 
Result so far: 88885.1976
Deduct 5190 from 5950 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 13:
If we divide 7600 by 865, we get 8 and a remainder of 680.
Record the quotient 8 as the next digit in the result. 
Result so far: 88885.19768
Subtracting 6920 from 7600 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 14:
865 goes into 6800 7 times with a remainder of 745.
The number 7 becomes the next digit in our result. 
Result so far: 88885.197687
The remainder is 745 after subtracting 6055 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Going ahead to step 15:
865 can be fit into 7450 8 times, resulting in a remainder of 530.
Write down 8 as next digit of the result. 
Result so far: 88885.1976878
Subtracting 6920 from 7450 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 16:
865 goes into 5300 6 times with a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 88885.19768786
If we subtract 5190 from 5300, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 88885.19768786 with a remainder of 1.1e-07.
