We're dividing 369830 by 9 
The aim is to understand the frequency of 9 in 369830.

Step 1:
9 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 9

Moving on to step 2:
9 can be fit into 36 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 36 from 36, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 9

Going ahead to step 3:
9 divided by 9 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 9

Moving on to step 4:
The number 9 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 410.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 9

Moving on to step 5:
9 goes into 83 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 4109.0
Deduct 81 from 83 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 9

Let's proceed to step 6:
If we divide 20 by 9, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 41092.0
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 9 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 41092.2
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 41092.22
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 41092.22 with a remainder of 0.002.
