We look at the division of 905734 by 85 
The aim is to understand the frequency of 85 in 905734.

Moving on to step 1:
When dividing 9 by 85, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 85

Advancing to step 2:
90 divided by 85 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 85 from 90 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 85

Advancing to step 3:
85 can be fit into 55 0 times, resulting in a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 55 and we're left with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 85

On to step 4:
85 can be fit into 557 6 times, resulting in a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 106.0
Deduct 510 from 557 and we're left with 47.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 85

Moving on to step 5:
473 divided by 85 is 5 with a remainder of 48.
The next digit of our result is 5. 
Result so far: 1065.0
Subtracting 425 from 473 leaves us with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 85

Going ahead to step 6:
484 divided by 85 is 5 with a remainder of 59.
The next digit of our result is 5. 
Result so far: 10655.0
Subtract 425 from 484 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
When dividing 590 by 85, we get 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 10655.6
If we subtract 510 from 590, 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.

Going ahead to step 8:
When dividing 800 by 85, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 10655.69
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 10655.694
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.

On to step 10:
If we divide 100 by 85, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 10655.6941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
85 can be fit into 150 1 times, resulting in a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 10655.69411
Deduct 85 from 150 and we're left 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.

Our division results in 10655.69411 with a remaining 6.5e-05.
