28539646 divided by 252 
The aim is to understand the frequency of 252 in 28539646.

On to step 1:
The number 252 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 252

Let's proceed to step 2:
When dividing 28 by 252, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 252

On to step 3:
252 goes into 285 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 252 from 285 leaves us with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 252

On to step 4:
252 can be fit into 333 1 times, resulting in a remainder of 81.
The next digit of our result is 1. 
Result so far: 11.0
If we take 252 away from 333, we end up with 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 252

Step 5:
When dividing 819 by 252, we get 3 with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Deduct 756 from 819 and we're left with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 252

Let's proceed to step 6:
636 divided by 252 is 2 with a remainder of 132.
The next digit of our result is 2. 
Result so far: 1132.0
The remainder is 132 after subtracting 504 from 636.
Bring next digit (4) of the dividend behind the 132 and repeat the process: 1324 / 252

Advancing to step 7:
When dividing 1324 by 252, we get 5 with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 11325.0
If we subtract 1260 from 1324, we get 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 252

Going ahead to step 8:
When dividing 646 by 252, we get 2 with a remainder of 142.
Put 2 as the next digit of the answer. 
Result so far: 113252.0
If we subtract 504 from 646, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 9:
252 goes into 1420 5 times with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 113252.5
The remainder is 160 after subtracting 1260 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
252 can be fit into 1600 6 times, resulting in a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 113252.56
Subtracting 1512 from 1600 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
880 divided by 252 is 3 with a remainder of 124.
Put 3 as the next digit of the answer. 
Result so far: 113252.563
If we subtract 756 from 880, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 12:
1240 divided by 252 is 4 with a remainder of 232.
Record the quotient 4 as the next digit in the result. 
Result so far: 113252.5634
Subtract 1008 from 1240 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 13:
The number 252 fits into 2320 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 113252.56349
Subtract 2268 from 2320 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
The number 252 fits into 520 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 113252.563492
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
160 divided by 252 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 113252.563492
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 16:
If we divide 1600 by 252, we get 6 and a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 113252.56349206
Deduct 1512 from 1600 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 113252.56349206 and a remainder of 8.8e-08.
