We're dividing 731070 by 9 
The aim is to understand the frequency of 9 in 731070.

Going ahead to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 9

Let's proceed to step 2:
The number 9 fits into 73 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 72 from 73, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 9

Step 3:
9 goes into 11 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 9 away from 11, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 9

Step 4:
9 goes into 20 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 812.0
Subtract 18 from 20 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 9

Advancing to step 5:
The number 9 fits into 27 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 8123.0
If we subtract 27 from 27, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 9

Advancing to step 6:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 81230.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 9, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 81230.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
9 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 81230.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 81230.0 with a remaining 0.0.
