307749 divided by 9 
The aim is to understand the frequency of 9 in 307749.

On to step 1:
If we divide 3 by 9, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 9

Advancing to step 2:
The number 9 fits into 30 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 27 from 30 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 9

Let's proceed to step 3:
The number 9 fits into 37 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 36 from 37 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 9

Going ahead to step 4:
When dividing 17 by 9, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 341.0
If we take 9 away from 17, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 9

Advancing to step 5:
The number 9 fits into 84 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 3419.0
If we subtract 81 from 84, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 9

Moving on to step 6:
9 goes into 39 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 34194.0
If we subtract 36 from 39, we 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.

Going ahead to step 7:
When dividing 30 by 9, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 34194.3
Deduct 27 from 30 and we're left 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.

On to step 8:
When dividing 30 by 9, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 34194.33
If we subtract 27 from 30, we 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 outcome is 34194.33, with a leftover of 0.003.
