Let's divide 420220 by 85
The aim is to understand the frequency of 85 in 420220.

Advancing to step 1:
If we divide 4 by 85, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 85

Going ahead to step 2:
The number 85 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 85

On to step 3:
When dividing 420 by 85, we get 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 340 from 420 and we're left with 80.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 85

On to step 4:
802 divided by 85 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 765 from 802 and we're left with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 85

Advancing to step 5:
85 goes into 372 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 494.0
If we take 340 away from 372, we end up with 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 85

Step 6:
The number 85 fits into 320 3 times, leaving a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 4943.0
The remainder is 65 after subtracting 255 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
When dividing 650 by 85, we get 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 4943.7
If we subtract 595 from 650, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
If we divide 550 by 85, we get 6 and a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 4943.76
If we subtract 510 from 550, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 85, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 4943.764
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.

Step 10:
The number 85 fits into 600 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 4943.7647
If we take 595 away from 600, we end up 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.

Let's proceed to step 11:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4943.7647
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 12:
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: 4943.764705
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.

Advancing to step 13:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 4943.7647058
If we subtract 680 from 750, we 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.

On to step 14:
If we divide 700 by 85, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 4943.76470588
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 final result is 4943.76470588 with a remainder of 2e-08.
