We divide 939971 by 9
The aim is to understand the frequency of 9 in 939971.

Step 1:
The number 9 fits into 9 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 9 from 9 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 9

Advancing to step 2:
If we divide 3 by 9, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 9

On to step 3:
The number 9 fits into 39 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we take 36 away from 39, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 9

On to step 4:
If we divide 39 by 9, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 1044.0
Subtracting 36 from 39 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 9

On to step 5:
9 can be fit into 37 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 10444.0
The remainder is 1 after subtracting 36 from 37.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 9

Step 6:
The number 9 fits into 11 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 104441.0
If we subtract 9 from 11, we 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 7:
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: 104441.2
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 9 fits into 20 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 104441.22
If we subtract 18 from 20, we 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.

In conclusion, the division gives 104441.22 with a balance of 0.002.
