We divide 211213 by 85
The aim is to understand the frequency of 85 in 211213.

On to step 1:
85 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 85

On to step 2:
The number 85 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 85

Going ahead to step 3:
When dividing 211 by 85, we get 2 with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 170 from 211, we get 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 85

Let's proceed to step 4:
When dividing 412 by 85, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 72 after subtracting 340 from 412.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 85

Let's proceed to step 5:
85 can be fit into 721 8 times, resulting in a remainder of 41.
The next digit of our result is 8. 
Result so far: 248.0
The remainder is 41 after subtracting 680 from 721.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 85

Advancing to step 6:
413 divided by 85 is 4 with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 2484.0
The remainder is 73 after subtracting 340 from 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
85 goes into 730 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 2484.8
The remainder is 50 after subtracting 680 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
85 goes into 500 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 2484.85
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.

Advancing to step 9:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 2484.858
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
700 divided by 85 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 2484.8588
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 2484.8588, and the remainder is 0.0002.
