We look at the division of 57758 by 9 
The aim is to understand the frequency of 9 in 57758.

On to step 1:
The number 9 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 9

Step 2:
The number 9 fits into 57 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 54 from 57 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 9

Step 3:
If we divide 37 by 9, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 64.0
Deduct 36 from 37 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 9

Let's proceed to step 4:
The number 9 fits into 15 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 641.0
Subtract 9 from 15 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 9

Advancing to step 5:
9 can be fit into 68 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 6417.0
Subtract 63 from 68 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 6:
50 divided by 9 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6417.5
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
9 can be fit into 50 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6417.55
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 6417.55, and the remainder is 0.005.
