We look at the division of 212822 by 57 
The aim is to understand the frequency of 57 in 212822.

Going ahead to step 1:
57 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 57

On to step 2:
If we divide 21 by 57, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 57

Moving on to step 3:
If we divide 212 by 57, we get 3 and a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 171 from 212 leaves us with 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 57

On to step 4:
If we divide 418 by 57, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 399 from 418 leaves us with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 57

Advancing to step 5:
When dividing 192 by 57, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
The remainder is 21 after subtracting 171 from 192.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 57

Moving on to step 6:
212 divided by 57 is 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 3733.0
If we subtract 171 from 212, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
When dividing 410 by 57, we get 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 3733.7
If we subtract 399 from 410, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
57 goes into 110 1 times with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 3733.71
If we subtract 57 from 110, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
57 goes into 530 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 3733.719
If we subtract 513 from 530, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
57 goes into 170 2 times with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 3733.7192
Deduct 114 from 170 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
57 can be fit into 560 9 times, resulting in a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 3733.71929
If we take 513 away from 560, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 12:
The number 57 fits into 470 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 3733.719298
Subtract 456 from 470 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
57 can be fit into 140 2 times, resulting in a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 3733.7192982
Subtract 114 from 140 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
57 can be fit into 260 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 3733.71929824
Subtract 228 from 260 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 3733.71929824 with a remaining 3.2e-08.
