We're dividing 606681 by 85 
The aim is to understand the frequency of 85 in 606681.

On to step 1:
If we divide 6 by 85, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 85

Let's proceed to step 2:
The number 85 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 85

Advancing to step 3:
The number 85 fits into 606 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 595 from 606 leaves us with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 85

Moving on to step 4:
85 can be fit into 116 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 85 away from 116, we end up with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 85

Moving on to step 5:
85 can be fit into 318 3 times, resulting in a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 713.0
Subtracting 255 from 318 leaves us with 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 85

Step 6:
The number 85 fits into 631 7 times, leaving a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 7137.0
If we subtract 595 from 631, we 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.

Going ahead to step 7:
If we divide 360 by 85, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 7137.4
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.

Step 8:
85 can be fit into 200 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 7137.42
Subtracting 170 from 200 leaves us 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.

Let's proceed to step 9:
300 divided by 85 is 3 with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 7137.423
If we subtract 255 from 300, we get 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:
If we divide 450 by 85, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7137.4235
Deduct 425 from 450 and we're left 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 11:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 7137.42352
If we take 170 away from 250, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
If we divide 800 by 85, we get 9 and a remainder of 35.
The next digit of our result is 9. 
Result so far: 7137.423529
If we subtract 765 from 800, 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.

On to step 13:
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: 7137.4235294
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.

Moving on to step 14:
85 can be fit into 100 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 7137.42352941
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 7137.42352941 and a remainder of 1.5e-08.
