We look at the division of 305739 by 85 
The aim is to understand the frequency of 85 in 305739.

Going ahead to step 1:
If we divide 3 by 85, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 85

Advancing to step 2:
85 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 85

Going ahead to step 3:
85 can be fit into 305 3 times, resulting in a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 255 from 305 to get 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 85

On to step 4:
The number 85 fits into 507 5 times, leaving a remainder of 82.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 425 away from 507, we end up with 82.
Include the next digit (3) from the dividend after 82, then repeat: 823 / 85

Let's proceed to step 5:
The number 85 fits into 823 9 times, leaving a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 359.0
Deduct 765 from 823 and we're left with 58.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 85

Let's proceed to step 6:
When dividing 589 by 85, we get 6 with a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 3596.0
Subtracting 510 from 589 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
85 goes into 790 9 times with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 3596.9
If we subtract 765 from 790, we 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.

Advancing to step 8:
250 divided by 85 is 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 3596.92
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 9:
85 goes into 800 9 times with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 3596.929
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.

Moving on to step 10:
The number 85 fits into 350 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 3596.9294
Subtract 340 from 350 to get 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 11:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 3596.92941
Subtracting 85 from 100 leaves us 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.

On to step 12:
150 divided by 85 is 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 3596.929411
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 3596.929411 with a balance of 6.5e-06.
