Let's divide 905207 by 9
The aim is to understand the frequency of 9 in 905207.

Moving on to step 1:
The number 9 fits into 9 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 9 from 9, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 9

Going ahead to step 2:
If we divide 0 by 9, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 9

Advancing to step 3:
9 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 9

Going ahead to step 4:
When dividing 52 by 9, we get 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 1005.0
Deduct 45 from 52 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 9

On to step 5:
If we divide 70 by 9, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 10057.0
Deduct 63 from 70 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 9

Moving on to step 6:
9 can be fit into 77 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 100578.0
The remainder is 5 after subtracting 72 from 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 100578.5
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 9 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 100578.55
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 100578.55 and a remainder of 0.005.
