Let's divide 420415 by 85
The aim is to understand the frequency of 85 in 420415.

Let's proceed to step 1:
85 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 85

Moving on to step 2:
When dividing 42 by 85, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 85

Going ahead to step 3:
420 divided by 85 is 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 340 from 420 to get 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 85

Advancing to step 4:
85 goes into 804 9 times with a remainder of 39.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 765 from 804 leaves us with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 85

Let's proceed to step 5:
The number 85 fits into 391 4 times, leaving a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
If we take 340 away from 391, we end up with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 85

Step 6:
The number 85 fits into 515 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 4946.0
The remainder is 5 after subtracting 510 from 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 85, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4946.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
When dividing 500 by 85, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4946.05
Deduct 425 from 500 and we're left 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.

Moving on to step 9:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 4946.058
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
85 goes into 700 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 4946.0588
If we take 680 away from 700, we end up with 20.
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 4946.0588, and the remainder is 0.0002.
