We're dividing 37128089 by 9 
The aim is to understand the frequency of 9 in 37128089.

On to step 1:
9 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 9

On to step 2:
If we divide 37 by 9, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 36 from 37, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 9

Advancing to step 3:
The number 9 fits into 11 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtract 9 from 11 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 9

On to step 4:
9 goes into 22 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 412.0
The remainder is 4 after subtracting 18 from 22.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 9

Going ahead to step 5:
The number 9 fits into 48 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 4125.0
The remainder is 3 after subtracting 45 from 48.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Advancing to step 6:
When dividing 30 by 9, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 41253.0
Subtract 27 from 30 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 9

Moving on to step 7:
9 goes into 38 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 412534.0
The remainder is 2 after subtracting 36 from 38.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

On to step 8:
The number 9 fits into 29 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 4125343.0
Subtract 27 from 29 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.

Moving on to step 9:
9 goes into 20 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 4125343.2
Subtracting 18 from 20 leaves us 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.

On to step 10:
9 goes into 20 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 4125343.22
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.

In conclusion, the division gives 4125343.22 with a balance of 0.002.
