Let's divide 856894 by 9
The aim is to understand the frequency of 9 in 856894.

Let's proceed to step 1:
9 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
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 9

Advancing to step 2:
The number 9 fits into 85 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 81 from 85, we get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 9

Moving on to step 3:
If we divide 46 by 9, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we subtract 45 from 46, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 9

Going ahead to step 4:
The number 9 fits into 18 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 952.0
Subtracting 18 from 18 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 9

Going ahead to step 5:
9 goes into 9 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 9521.0
Subtract 9 from 9 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 9

Step 6:
9 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 95210.0
Subtract 0 from 4 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 9, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 95210.4
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
9 can be fit into 40 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 95210.44
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 95210.44 with a remaining 0.004.
