80218029 divided by 252 
The aim is to understand the frequency of 252 in 80218029.

Let's proceed to step 1:
252 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 252

Step 2:
252 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 252

Moving on to step 3:
The number 252 fits into 802 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 756 from 802 leaves us with 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 252

Going ahead to step 4:
The number 252 fits into 461 1 times, leaving a remainder of 209.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 252 from 461, we get 209.
Grab the next digit (8) from the dividend, add it to 209, then carry on: 2098 / 252

Going ahead to step 5:
When dividing 2098 by 252, we get 8 with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 318.0
The remainder is 82 after subtracting 2016 from 2098.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 252

Going ahead to step 6:
252 goes into 820 3 times with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 3183.0
Subtracting 756 from 820 leaves us with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 252

Advancing to step 7:
If we divide 642 by 252, we get 2 and a remainder of 138.
The next digit of our result is 2. 
Result so far: 31832.0
Subtracting 504 from 642 leaves us with 138.
Fetch the next digit (9) from the dividend, attach it to 138 and continue: 1389 / 252

Advancing to step 8:
252 goes into 1389 5 times with a remainder of 129.
The next digit of our result is 5. 
Result so far: 318325.0
Subtracting 1260 from 1389 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 9:
252 can be fit into 1290 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 318325.5
If we take 1260 away from 1290, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
300 divided by 252 is 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 318325.51
If we subtract 252 from 300, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
The number 252 fits into 480 1 times, leaving a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 318325.511
The remainder is 228 after subtracting 252 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The quotient of the division is 318325.511, and the remainder is 0.0228.
