We look at the division of 890155 by 85 
The aim is to understand the frequency of 85 in 890155.

Going ahead to step 1:
The number 85 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 85

Let's proceed to step 2:
85 can be fit into 89 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 85 from 89 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 85

Advancing to step 3:
The number 85 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 85

Step 4:
85 goes into 401 4 times with a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtracting 340 from 401 leaves us with 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 85

Going ahead to step 5:
If we divide 615 by 85, we get 7 and a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 1047.0
Deduct 595 from 615 and we're left with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 85

Let's proceed to step 6:
If we divide 205 by 85, we get 2 and a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 10472.0
If we subtract 170 from 205, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
85 goes into 350 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 10472.4
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 85 fits into 100 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 10472.41
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
85 goes into 150 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 10472.411
Deduct 85 from 150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 10472.411, with a leftover of 0.0065.
