We look at the division of 9304 by 85 
The aim is to understand the frequency of 85 in 9304.

Going ahead to step 1:
9 divided by 85 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 85

Let's proceed to step 2:
93 divided by 85 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 85 from 93, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 85

Step 3:
85 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 85

Step 4:
When dividing 804 by 85, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 109.0
Subtract 765 from 804 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 5:
390 divided by 85 is 4 with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 109.4
Deduct 340 from 390 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 6:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 109.45
If we take 425 away from 500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
If we divide 750 by 85, we get 8 and a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 109.458
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
700 divided by 85 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 109.4588
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 109.4588, and the remainder is 0.0002.
