We look at the division of 770211 by 85 
The aim is to understand the frequency of 85 in 770211.

Step 1:
85 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 85

Moving on to step 2:
85 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 85

On to step 3:
When dividing 770 by 85, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 765 from 770 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 85

Step 4:
85 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 85

Let's proceed to step 5:
If we divide 521 by 85, we get 6 and a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 906.0
Subtracting 510 from 521 leaves us with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 85

Going ahead to step 6:
85 goes into 111 1 times with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 9061.0
If we subtract 85 from 111, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
When dividing 260 by 85, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 9061.3
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9061.3
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 9061.305
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
750 divided by 85 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 9061.3058
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
When dividing 700 by 85, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 9061.30588
Subtracting 680 from 700 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.

Our division results in 9061.30588 with a remaining 2e-05.
