We're dividing 53301284 by 212 
The aim is to understand the frequency of 212 in 53301284.

Going ahead to step 1:
When dividing 5 by 212, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 212

Going ahead to step 2:
53 divided by 212 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 212

Moving on to step 3:
If we divide 533 by 212, we get 2 and a remainder of 109.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 424 from 533 to get 109.
Bring next digit (0) of the dividend behind the 109 and repeat the process: 1090 / 212

Moving on to step 4:
212 can be fit into 1090 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 1060 away from 1090, we end up with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 212

Going ahead to step 5:
If we divide 301 by 212, we get 1 and a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 251.0
Deduct 212 from 301 and we're left with 89.
Include the next digit (2) from the dividend after 89, then repeat: 892 / 212

Step 6:
The number 212 fits into 892 4 times, leaving a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 2514.0
Subtracting 848 from 892 leaves us with 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 212

Let's proceed to step 7:
448 divided by 212 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 25142.0
Deduct 424 from 448 and we're left with 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 212

Let's proceed to step 8:
When dividing 244 by 212, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 251421.0
Subtracting 212 from 244 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
212 can be fit into 320 1 times, resulting in a remainder of 108.
Record the quotient 1 as the next digit in the result. 
Result so far: 251421.1
If we take 212 away from 320, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 10:
The number 212 fits into 1080 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 251421.15
Subtract 1060 from 1080 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
When dividing 200 by 212, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 251421.15
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
When dividing 2000 by 212, we get 9 with a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 251421.1509
Subtract 1908 from 2000 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 13:
When dividing 920 by 212, we get 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 251421.15094
Subtracting 848 from 920 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
720 divided by 212 is 3 with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 251421.150943
Subtracting 636 from 720 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 15:
If we divide 840 by 212, we get 3 and a remainder of 204.
The number 3 becomes the next digit in our result. 
Result so far: 251421.1509433
If we subtract 636 from 840, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

In conclusion, the division gives 251421.1509433 with a balance of 2.04e-06.
