We divide 910945 by 9
The aim is to understand the frequency of 9 in 910945.

Let's proceed to step 1:
The number 9 fits into 9 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 9 away from 9, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 9

Going ahead to step 2:
1 divided by 9 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 1, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 9

Moving on to step 3:
When dividing 10 by 9, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we take 9 away from 10, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 9

Step 4:
The number 9 fits into 19 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1012.0
Deduct 18 from 19 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 9

Advancing to step 5:
The number 9 fits into 14 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 10121.0
If we subtract 9 from 14, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 9

Let's proceed to step 6:
9 goes into 55 6 times with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 101216.0
Subtract 54 from 55 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 9, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 101216.1
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.

Going ahead to step 8:
If we divide 10 by 9, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 101216.11
Subtract 9 from 10 to get 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 101216.11, and the remainder is 0.001.
