We're dividing 978593 by 85 
The aim is to understand the frequency of 85 in 978593.

Let's proceed to step 1:
9 divided by 85 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 85

Step 2:
85 can be fit into 97 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 85 from 97 to get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 85

Going ahead to step 3:
When dividing 128 by 85, we get 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 85 from 128, we get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 85

Moving on to step 4:
When dividing 435 by 85, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtract 425 from 435 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 85

Step 5:
109 divided by 85 is 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1151.0
Subtracting 85 from 109 leaves us with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 85

Going ahead to step 6:
243 divided by 85 is 2 with a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 11512.0
Deduct 170 from 243 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
If we divide 730 by 85, we get 8 and a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 11512.8
Subtracting 680 from 730 leaves us 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.

On to step 8:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 11512.85
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
When dividing 750 by 85, we get 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 11512.858
Deduct 680 from 750 and we're left with 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 10:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 11512.8588
If we take 680 away from 700, we end up 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.

After the division, we end up with 11512.8588 and a remainder of 0.0002.
