We're dividing 28254890 by 212 
The aim is to understand the frequency of 212 in 28254890.

Let's proceed to step 1:
212 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 212

Step 2:
When dividing 28 by 212, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 212

Step 3:
282 divided by 212 is 1 with a remainder of 70.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 212 from 282 and we're left with 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 212

Let's proceed to step 4:
705 divided by 212 is 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 636 from 705 to get 69.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 212

Step 5:
When dividing 694 by 212, we get 3 with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
If we take 636 away from 694, we end up with 58.
Include the next digit (8) from the dividend after 58, then repeat: 588 / 212

Advancing to step 6:
588 divided by 212 is 2 with a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 1332.0
If we subtract 424 from 588, we get 164.
Append the next digit (9) from the dividend to 164 and continue with: 1649 / 212

Advancing to step 7:
212 goes into 1649 7 times with a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 13327.0
Deduct 1484 from 1649 and we're left with 165.
Take the next digit (0) from the dividend and append it to 165, then repeat: 1650 / 212

Advancing to step 8:
1650 divided by 212 is 7 with a remainder of 166.
Use 7 as the next digit of our solution. 
Result so far: 133277.0
Subtract 1484 from 1650 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 9:
When dividing 1660 by 212, we get 7 with a remainder of 176.
Write down 7 as next digit of the result. 
Result so far: 133277.7
Subtracting 1484 from 1660 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 10:
212 can be fit into 1760 8 times, resulting in a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 133277.78
Subtract 1696 from 1760 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
If we divide 640 by 212, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 133277.783
Subtract 636 from 640 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
The number 212 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 133277.783
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
400 divided by 212 is 1 with a remainder of 188.
The number 1 becomes the next digit in our result. 
Result so far: 133277.78301
Subtracting 212 from 400 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 14:
1880 divided by 212 is 8 with a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 133277.783018
Subtract 1696 from 1880 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
When dividing 1840 by 212, we get 8 with a remainder of 144.
Record the quotient 8 as the next digit in the result. 
Result so far: 133277.7830188
Subtract 1696 from 1840 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 133277.7830188, with a leftover of 1.44e-06.
