Let's divide 602953 by 9
The aim is to understand the frequency of 9 in 602953.

Going ahead to step 1:
6 divided by 9 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 9

Step 2:
9 goes into 60 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 54 away from 60, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 9

Moving on to step 3:
If we divide 62 by 9, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Deduct 54 from 62 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 9

Step 4:
When dividing 89 by 9, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 669.0
Deduct 81 from 89 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 9

Step 5:
When dividing 85 by 9, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 6699.0
If we take 81 away from 85, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

Advancing to step 6:
43 divided by 9 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 66994.0
If we subtract 36 from 43, we 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.

On to step 7:
If we divide 70 by 9, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 66994.7
Deduct 63 from 70 and we're left 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.

Let's proceed to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 66994.77
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 66994.77 and a remainder of 0.007.
