We look at the division of 8668585 by 885 
The aim is to understand the frequency of 885 in 8668585.

On to step 1:
8 divided by 885 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 885

Let's proceed to step 2:
If we divide 86 by 885, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 885

Going ahead to step 3:
885 can be fit into 866 0 times, resulting in a remainder of 866.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 866 to get 866.
Grab the next digit (8) from the dividend, add it to 866, then carry on: 8668 / 885

Let's proceed to step 4:
885 can be fit into 8668 9 times, resulting in a remainder of 703.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 703 after subtracting 7965 from 8668.
Fetch the next digit (5) from the dividend, attach it to 703 and continue: 7035 / 885

Let's proceed to step 5:
If we divide 7035 by 885, we get 7 and a remainder of 840.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 6195 from 7035 leaves us with 840.
Fetch the next digit (8) from the dividend, attach it to 840 and continue: 8408 / 885

Moving on to step 6:
885 goes into 8408 9 times with a remainder of 443.
Record the quotient 9 as the next digit in the result. 
Result so far: 979.0
If we take 7965 away from 8408, we end up with 443.
Take the next digit (5) from the dividend and append it to 443, then repeat: 4435 / 885

Going ahead to step 7:
When dividing 4435 by 885, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 9795.0
The remainder is 10 after subtracting 4425 from 4435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
885 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 9795.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 9:
1000 divided by 885 is 1 with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 9795.01
If we take 885 away from 1000, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 10:
1150 divided by 885 is 1 with a remainder of 265.
Put 1 as the next digit of the answer. 
Result so far: 9795.011
Subtracting 885 from 1150 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Our division results in 9795.011 with a remaining 0.0265.
