We look at the division of 671451 by 85 
The aim is to understand the frequency of 85 in 671451.

Step 1:
If we divide 6 by 85, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 85

Moving on to step 2:
67 divided by 85 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 85

Advancing to step 3:
When dividing 671 by 85, we get 7 with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 76 after subtracting 595 from 671.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 85

Let's proceed to step 4:
If we divide 764 by 85, we get 8 and a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 84 after subtracting 680 from 764.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 85

Going ahead to step 5:
85 can be fit into 845 9 times, resulting in a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 789.0
The remainder is 80 after subtracting 765 from 845.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 85

Step 6:
801 divided by 85 is 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 7899.0
Subtract 765 from 801 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
360 divided by 85 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 7899.4
Subtracting 340 from 360 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.

Let's proceed to step 8:
85 goes into 200 2 times with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 7899.42
If we take 170 away from 200, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 85 is 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 7899.423
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
450 divided by 85 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 7899.4235
Subtract 425 from 450 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
85 goes into 250 2 times with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 7899.42352
The remainder is 80 after subtracting 170 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
800 divided by 85 is 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 7899.423529
If we take 765 away from 800, we end up with 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 13:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 7899.4235294
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 7899.42352941
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.

In conclusion, the division gives 7899.42352941 with a balance of 1.5e-08.
