We divide 433737 by 9
The aim is to understand the frequency of 9 in 433737.

Advancing to step 1:
4 divided by 9 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

Going ahead to step 2:
43 divided by 9 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 36 from 43, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 9

Advancing to step 3:
If we divide 73 by 9, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 72 from 73 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 9

Step 4:
The number 9 fits into 17 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 481.0
If we take 9 away from 17, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 9

On to step 5:
83 divided by 9 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 4819.0
Subtracting 81 from 83 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 9

Going ahead to step 6:
9 can be fit into 27 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 48193.0
The remainder is 0 after subtracting 27 from 27.
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 7:
9 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48193.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48193.0
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 48193.0, with a leftover of 0.0.
