842686 divided by 9 
The aim is to understand the frequency of 9 in 842686.

Going ahead to step 1:
9 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 9

On to step 2:
When dividing 84 by 9, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 81 away from 84, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 9

Moving on to step 3:
9 can be fit into 32 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 93.0
If we take 27 away from 32, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 9

Going ahead to step 4:
56 divided by 9 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 936.0
If we take 54 away from 56, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 9

Advancing to step 5:
28 divided by 9 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 9363.0
If we take 27 away from 28, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 9

Advancing to step 6:
The number 9 fits into 16 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 93631.0
Subtracting 9 from 16 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 9 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 93631.7
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
9 can be fit into 70 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 93631.77
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 93631.77, and the remainder is 0.007.
