429654 ÷ 9 
The aim is to understand the frequency of 9 in 429654.

Going ahead to step 1:
4 divided by 9 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 9

Moving on to step 2:
The number 9 fits into 42 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 6 after subtracting 36 from 42.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 9

Step 3:
9 goes into 69 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 63 away from 69, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 9

Step 4:
9 can be fit into 66 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 477.0
If we subtract 63 from 66, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 9

Advancing to step 5:
If we divide 35 by 9, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 4773.0
Subtract 27 from 35 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 9

Let's proceed to step 6:
The number 9 fits into 84 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 47739.0
Subtracting 81 from 84 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 9 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 47739.3
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
If we divide 30 by 9, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 47739.33
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 47739.33 with a remainder of 0.003.
