876646 ÷ 89 
The aim is to understand the frequency of 89 in 876646.

Step 1:
89 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
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 89

On to step 2:
89 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 89

On to step 3:
The number 89 fits into 876 9 times, leaving a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 801 from 876 leaves us with 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 89

Step 4:
The number 89 fits into 756 8 times, leaving a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtract 712 from 756 to get 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 89

Advancing to step 5:
444 divided by 89 is 4 with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 984.0
Subtracting 356 from 444 leaves us with 88.
Grab the next digit (6) from the dividend, add it to 88, then carry on: 886 / 89

Let's proceed to step 6:
The number 89 fits into 886 9 times, leaving a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 9849.0
Subtracting 801 from 886 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 7:
If we divide 850 by 89, we get 9 and a remainder of 49.
The next digit of our result is 9. 
Result so far: 9849.9
Subtracting 801 from 850 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 8:
89 goes into 490 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 9849.95
If we subtract 445 from 490, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
89 goes into 450 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 9849.955
Subtracting 445 from 450 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 9849.955 with a remainder of 0.0005.
