854043 divided by 9 
The aim is to understand the frequency of 9 in 854043.

On to step 1:
8 divided by 9 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 9

Let's proceed to step 2:
9 goes into 85 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 81 from 85 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 9

Going ahead to step 3:
The number 9 fits into 44 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 36 away from 44, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 9

Step 4:
When dividing 80 by 9, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 948.0
If we subtract 72 from 80, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 9

Let's proceed to step 5:
The number 9 fits into 84 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9489.0
If we take 81 away from 84, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 9

On to step 6:
When dividing 33 by 9, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 94893.0
The remainder is 6 after subtracting 27 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 9, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 94893.6
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 9 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 94893.66
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 94893.66, with a leftover of 0.006.
