753609 ÷ 9 
The aim is to understand the frequency of 9 in 753609.

On to step 1:
9 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 9

Step 2:
9 goes into 75 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 72 from 75, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 9

Advancing to step 3:
The number 9 fits into 33 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we take 27 away from 33, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 9

Going ahead to 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: 837.0
Subtract 63 from 66 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 9

On to step 5:
30 divided by 9 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 8373.0
Subtract 27 from 30 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 9

On to step 6:
9 goes into 39 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 83734.0
If we take 36 away from 39, 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.

Step 7:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 83734.3
Subtracting 27 from 30 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.

Going ahead 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: 83734.33
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 83734.33, and the remainder is 0.003.
