We're dividing 74274050 by 9 
The aim is to understand the frequency of 9 in 74274050.

Step 1:
9 goes into 7 0 times with 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.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 9

Advancing to step 2:
74 divided by 9 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 72 away from 74, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 9

On to step 3:
When dividing 22 by 9, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 18 from 22 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 9

Moving on to step 4:
When dividing 47 by 9, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 825.0
If we subtract 45 from 47, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 9

On to step 5:
24 divided by 9 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 8252.0
Deduct 18 from 24 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 9

On to step 6:
9 goes into 60 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 82526.0
The remainder is 6 after subtracting 54 from 60.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 9

Step 7:
The number 9 fits into 65 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 825267.0
If we take 63 away from 65, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 9

Let's proceed to step 8:
When dividing 20 by 9, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 8252672.0
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
20 divided by 9 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 8252672.2
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
The number 9 fits into 20 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 8252672.22
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 8252672.22, and the remainder is 0.002.
