17128018 ÷ 9 
The aim is to understand the frequency of 9 in 17128018.

Going ahead to step 1:
If we divide 1 by 9, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 9

Step 2:
If we divide 17 by 9, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we take 9 away from 17, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 9

On to step 3:
9 goes into 81 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 81 from 81, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 9

Moving on to step 4:
The number 9 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 9

Going ahead to step 5:
If we divide 28 by 9, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1903.0
If we take 27 away from 28, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 9

Advancing to step 6:
9 goes into 10 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 19031.0
Subtracting 9 from 10 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 9

Moving on to step 7:
9 goes into 11 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 190311.0
The remainder is 2 after subtracting 9 from 11.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 9

Advancing to step 8:
The number 9 fits into 28 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1903113.0
If we take 27 away from 28, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 9, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1903113.1
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
9 can be fit into 10 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1903113.11
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 1903113.11, and the remainder is 0.001.
