Let's divide 807440 by 85
The aim is to understand the frequency of 85 in 807440.

Going ahead to step 1:
If we divide 8 by 85, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 85

On to step 2:
85 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 85

Let's proceed to step 3:
If we divide 807 by 85, we get 9 and a remainder of 42.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 765 from 807 to get 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 85

Step 4:
When dividing 424 by 85, we get 4 with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we subtract 340 from 424, we get 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 85

Going ahead to step 5:
85 can be fit into 844 9 times, resulting in a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 949.0
Deduct 765 from 844 and we're left with 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 85

Step 6:
When dividing 790 by 85, we get 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 9499.0
Subtract 765 from 790 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.

On to step 7:
If we divide 250 by 85, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 9499.2
The remainder is 80 after subtracting 170 from 250.
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 8:
The number 85 fits into 800 9 times, leaving a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 9499.29
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 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: 9499.294
Deduct 340 from 350 and we're left 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 10:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 9499.2941
If we take 85 away from 100, we end up 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.

Advancing to step 11:
When dividing 150 by 85, we get 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 9499.29411
The remainder is 65 after subtracting 85 from 150.
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 9499.29411 with a remainder of 6.5e-05.
