35964616 ÷ 9 
The aim is to understand the frequency of 9 in 35964616.

Going ahead to step 1:
The number 9 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 9

Let's proceed to step 2:
The number 9 fits into 35 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 27 from 35 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 9

Advancing to step 3:
If we divide 89 by 9, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 81 from 89 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 9

Moving on to step 4:
When dividing 86 by 9, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 399.0
Subtract 81 from 86 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 9

Step 5:
The number 9 fits into 54 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 3996.0
If we take 54 away from 54, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 9

Moving on to step 6:
If we divide 6 by 9, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 39960.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 9

Going ahead to step 7:
The number 9 fits into 61 6 times, leaving a remainder of 7.
The next digit of our result is 6. 
Result so far: 399606.0
Subtracting 54 from 61 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 9

Advancing to step 8:
If we divide 76 by 9, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 3996068.0
Deduct 72 from 76 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
When dividing 40 by 9, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 3996068.4
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
9 goes into 40 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 3996068.44
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 3996068.44, and the remainder is 0.004.
