We look at the division of 12212216 by 529 
The aim is to understand the frequency of 529 in 12212216.

Let's proceed to step 1:
529 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 529

Moving on to step 2:
The number 529 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 529

Going ahead to step 3:
The number 529 fits into 122 0 times, leaving a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 122 to get 122.
Grab the next digit (1) from the dividend, add it to 122, then carry on: 1221 / 529

Let's proceed to step 4:
If we divide 1221 by 529, we get 2 and a remainder of 163.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1058 from 1221, we get 163.
Include the next digit (2) from the dividend after 163, then repeat: 1632 / 529

Step 5:
1632 divided by 529 is 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 45 after subtracting 1587 from 1632.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 529

Advancing to step 6:
529 can be fit into 452 0 times, resulting in a remainder of 452.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
Subtracting 0 from 452 leaves us with 452.
Grab the next digit (1) from the dividend, add it to 452, then carry on: 4521 / 529

On to step 7:
529 goes into 4521 8 times with a remainder of 289.
Record the quotient 8 as the next digit in the result. 
Result so far: 2308.0
Subtract 4232 from 4521 to get 289.
Fetch the next digit (6) from the dividend, attach it to 289 and continue: 2896 / 529

Moving on to step 8:
529 can be fit into 2896 5 times, resulting in a remainder of 251.
The number 5 becomes the next digit in our result. 
Result so far: 23085.0
Subtract 2645 from 2896 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 9:
The number 529 fits into 2510 4 times, leaving a remainder of 394.
The number 4 becomes the next digit in our result. 
Result so far: 23085.4
Subtracting 2116 from 2510 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 10:
3940 divided by 529 is 7 with a remainder of 237.
Record the quotient 7 as the next digit in the result. 
Result so far: 23085.47
Deduct 3703 from 3940 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 11:
The number 529 fits into 2370 4 times, leaving a remainder of 254.
Put 4 as the next digit of the answer. 
Result so far: 23085.474
Subtracting 2116 from 2370 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 12:
529 can be fit into 2540 4 times, resulting in a remainder of 424.
Write down 4 as next digit of the result. 
Result so far: 23085.4744
If we subtract 2116 from 2540, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

After the division, we end up with 23085.4744 and a remainder of 0.00424.
