388934 divided by 85 
The aim is to understand the frequency of 85 in 388934.

Let's proceed to step 1:
When dividing 3 by 85, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 85

On to step 2:
The number 85 fits into 38 0 times, leaving a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 85

On to step 3:
388 divided by 85 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 48 after subtracting 340 from 388.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 85

Going ahead to step 4:
85 can be fit into 489 5 times, resulting in a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 425 from 489 to get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 85

Going ahead to step 5:
85 can be fit into 643 7 times, resulting in a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 457.0
The remainder is 48 after subtracting 595 from 643.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 85

On to step 6:
The number 85 fits into 484 5 times, leaving a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 4575.0
The remainder is 59 after subtracting 425 from 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
590 divided by 85 is 6 with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 4575.6
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.

On to step 8:
85 goes into 800 9 times with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 4575.69
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.

Let's proceed to step 9:
If we divide 350 by 85, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4575.694
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.

Going ahead to step 10:
100 divided by 85 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 4575.6941
Subtract 85 from 100 to 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.

Step 11:
85 can be fit into 150 1 times, resulting in a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 4575.69411
If we take 85 away from 150, we end up 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.

The final outcome is 4575.69411, with a leftover of 6.5e-05.
