972558 ÷ 85 
The aim is to understand the frequency of 85 in 972558.

On to step 1:
If we divide 9 by 85, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 85

Let's proceed to step 2:
85 can be fit into 97 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 85 from 97 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 85

Going ahead to step 3:
The number 85 fits into 122 1 times, leaving a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 85 from 122, we get 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 85

Advancing to step 4:
375 divided by 85 is 4 with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we subtract 340 from 375, we get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 85

Moving on to step 5:
When dividing 355 by 85, we get 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 1144.0
The remainder is 15 after subtracting 340 from 355.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 85

Let's proceed to step 6:
158 divided by 85 is 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 11441.0
If we take 85 away from 158, we end up 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.

On to step 7:
When dividing 730 by 85, we get 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 11441.8
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:
500 divided by 85 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 11441.85
Subtracting 425 from 500 leaves us 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.

Let's proceed to step 9:
When dividing 750 by 85, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 11441.858
Subtract 680 from 750 to 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.

Going ahead to step 10:
If we divide 700 by 85, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 11441.8588
If we subtract 680 from 700, we get 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 final outcome is 11441.8588, with a leftover of 0.0002.
