We divide 660470 by 85
The aim is to understand the frequency of 85 in 660470.

On to step 1:
85 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 85

Let's proceed to step 2:
When dividing 66 by 85, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 85

On to step 3:
85 can be fit into 660 7 times, resulting in a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 595 away from 660, we end up with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 85

Step 4:
If we divide 654 by 85, we get 7 and a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 595 from 654 leaves us with 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 85

Moving on to step 5:
597 divided by 85 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 777.0
Subtract 595 from 597 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 85

On to step 6:
20 divided by 85 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7770.0
Subtract 0 from 20 to 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.

Going ahead to step 7:
If we divide 200 by 85, we get 2 and a remainder of 30.
The next digit of our result is 2. 
Result so far: 7770.2
Deduct 170 from 200 and we're left 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.

Moving on to step 8:
When dividing 300 by 85, we get 3 with a remainder of 45.
The next digit of our result is 3. 
Result so far: 7770.23
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.

Let's proceed to step 9:
450 divided by 85 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7770.235
If we take 425 away from 450, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
If we divide 250 by 85, we get 2 and a remainder of 80.
The next digit of our result is 2. 
Result so far: 7770.2352
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
When dividing 800 by 85, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 7770.23529
Deduct 765 from 800 and we're left 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.

Moving on to step 12:
350 divided by 85 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 7770.235294
Subtracting 340 from 350 leaves us 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.

Advancing to step 13:
100 divided by 85 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 7770.2352941
Subtracting 85 from 100 leaves us 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.

Moving on to step 14:
85 can be fit into 150 1 times, resulting in a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 7770.23529411
If we take 85 away from 150, we end up 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 result is 7770.23529411 with a remainder of 6.5e-08.
