We look at the division of 426379 by 85 
The aim is to understand the frequency of 85 in 426379.

Moving on to step 1:
The number 85 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 85

Let's proceed to step 2:
85 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 85

On to step 3:
The number 85 fits into 426 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 425 from 426 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 85

On to step 4:
85 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 85

Moving on to step 5:
85 goes into 137 1 times with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 501.0
If we subtract 85 from 137, we get 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 85

Step 6:
When dividing 529 by 85, we get 6 with a remainder of 19.
The next digit of our result is 6. 
Result so far: 5016.0
The remainder is 19 after subtracting 510 from 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
If we divide 190 by 85, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5016.2
The remainder is 20 after subtracting 170 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 85 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 5016.22
The remainder is 30 after subtracting 170 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 5016.22 with a remainder of 0.03.
