773587 divided by 85 
The aim is to understand the frequency of 85 in 773587.

On to step 1:
85 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 85

Moving on to step 2:
77 divided by 85 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 85

Advancing to step 3:
If we divide 773 by 85, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 765 from 773, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 85

Going ahead to step 4:
When dividing 85 by 85, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 85 from 85 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 85

On to step 5:
8 divided by 85 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 910.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 85

Going ahead to step 6:
If we divide 87 by 85, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 9101.0
Deduct 85 from 87 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
85 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 9101.0
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.

Step 8:
85 goes into 200 2 times with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 9101.02
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.

Step 9:
If we divide 300 by 85, we get 3 and a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 9101.023
The remainder is 45 after subtracting 255 from 300.
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:
85 can be fit into 450 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 9101.0235
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.

Let's proceed to step 11:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 9101.02352
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.

Let's proceed to step 12:
When dividing 800 by 85, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 9101.023529
Subtract 765 from 800 to 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.

Going ahead to step 13:
When dividing 350 by 85, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 9101.0235294
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.

Let's proceed to step 14:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 9101.02352941
If we subtract 85 from 100, we 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 9101.02352941 and a remainder of 1.5e-08.
