415875 divided by 85 
The aim is to understand the frequency of 85 in 415875.

Step 1:
4 divided by 85 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 85

Moving on to step 2:
41 divided by 85 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 85

Advancing to step 3:
If we divide 415 by 85, we get 4 and a remainder of 75.
The next digit of our result is 4. 
Result so far: 4.0
If we take 340 away from 415, we end up with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 85

Step 4:
85 goes into 758 8 times with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 680 from 758 and we're left with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 85

Step 5:
When dividing 787 by 85, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 489.0
If we subtract 765 from 787, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 85

Let's proceed to step 6:
225 divided by 85 is 2 with a remainder of 55.
The next digit of our result is 2. 
Result so far: 4892.0
The remainder is 55 after subtracting 170 from 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
The number 85 fits into 550 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 4892.6
Subtracting 510 from 550 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
When dividing 400 by 85, we get 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 4892.64
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
If we divide 600 by 85, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 4892.647
Deduct 595 from 600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
85 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4892.647
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 4892.64705
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 4892.647058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
700 divided by 85 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 4892.6470588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 4892.6470588, and the remainder is 2e-07.
