212052 ÷ 65 
The aim is to understand the frequency of 65 in 212052.

Going ahead to step 1:
When dividing 2 by 65, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 65

On to step 2:
65 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 65

Going ahead to step 3:
212 divided by 65 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 195 away from 212, we end up with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 65

Going ahead to step 4:
If we divide 170 by 65, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 130 from 170, we get 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 65

Moving on to step 5:
When dividing 405 by 65, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 326.0
Subtract 390 from 405 to get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 65

On to step 6:
65 can be fit into 152 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 3262.0
Deduct 130 from 152 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
The number 65 fits into 220 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 3262.3
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
The number 65 fits into 250 3 times, leaving a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 3262.33
Deduct 195 from 250 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 3262.33 with a remainder of 0.055.
