Let's divide 805851 by 9
The aim is to understand the frequency of 9 in 805851.

Step 1:
The number 9 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 9

Let's proceed to step 2:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 8 after subtracting 72 from 80.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 9

Going ahead to step 3:
9 goes into 85 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtracting 81 from 85 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 9

Let's proceed to step 4:
If we divide 48 by 9, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 895.0
If we subtract 45 from 48, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 9

On to step 5:
If we divide 35 by 9, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 8953.0
The remainder is 8 after subtracting 27 from 35.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 9

Step 6:
9 goes into 81 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 89539.0
Deduct 81 from 81 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 9, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 89539.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 9 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 89539.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 89539.0, with a leftover of 0.0.
