891377 divided by 9 
The aim is to understand the frequency of 9 in 891377.

Step 1:
If we divide 8 by 9, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 9

Moving on to step 2:
The number 9 fits into 89 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 81 from 89 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 9

Going ahead to step 3:
When dividing 81 by 9, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we take 81 away from 81, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 9

Advancing to step 4:
3 divided by 9 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 990.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 9

Step 5:
37 divided by 9 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 9904.0
If we take 36 away from 37, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 9

Going ahead to step 6:
The number 9 fits into 17 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 99041.0
Subtract 9 from 17 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
9 goes into 80 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 99041.8
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
80 divided by 9 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 99041.88
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 99041.88 with a balance of 0.008.
