We look at the division of 886532 by 89 
The aim is to understand the frequency of 89 in 886532.

Advancing to step 1:
89 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 89

Advancing to step 2:
89 can be fit into 88 0 times, resulting in a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Include the next digit (6) from the dividend after 88, then repeat: 886 / 89

Going ahead to step 3:
If we divide 886 by 89, we get 9 and a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 801 from 886, we get 85.
Include the next digit (5) from the dividend after 85, then repeat: 855 / 89

Step 4:
855 divided by 89 is 9 with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 801 from 855, we get 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 89

Let's proceed to step 5:
543 divided by 89 is 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 996.0
Deduct 534 from 543 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 89

Advancing to step 6:
89 can be fit into 92 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 9961.0
If we take 89 away from 92, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 89, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9961.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
89 can be fit into 300 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 9961.03
If we take 267 away from 300, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
89 goes into 330 3 times with a remainder of 63.
The next digit of our result is 3. 
Result so far: 9961.033
If we take 267 away from 330, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 9961.033, and the remainder is 0.0063.
