662574 divided by 9 
The aim is to understand the frequency of 9 in 662574.

Let's proceed to step 1:
9 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 9

Going ahead to step 2:
When dividing 66 by 9, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 63 from 66, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 9

Advancing to step 3:
When dividing 32 by 9, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 27 from 32 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 9

Let's proceed to step 4:
9 can be fit into 55 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 736.0
Deduct 54 from 55 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 9

Step 5:
9 can be fit into 17 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 7361.0
Subtracting 9 from 17 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 9

Advancing to step 6:
When dividing 84 by 9, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 73619.0
Deduct 81 from 84 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.

Let's proceed to step 7:
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: 73619.3
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.

On to step 8:
The number 9 fits into 30 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 73619.33
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.

Our division results in 73619.33 with a remaining 0.003.
