28737540 ÷ 252 
The aim is to understand the frequency of 252 in 28737540.

Step 1:
When dividing 2 by 252, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 252

On to step 2:
28 divided by 252 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 252

Step 3:
252 goes into 287 1 times with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 35 after subtracting 252 from 287.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 252

Let's proceed to step 4:
When dividing 353 by 252, we get 1 with a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 252 away from 353, we end up with 101.
Append the next digit (7) from the dividend to 101 and continue with: 1017 / 252

On to step 5:
If we divide 1017 by 252, we get 4 and a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtracting 1008 from 1017 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 252

Step 6:
When dividing 95 by 252, we get 0 with a remainder of 95.
The next digit of our result is 0. 
Result so far: 1140.0
Subtracting 0 from 95 leaves us with 95.
Bring next digit (4) of the dividend behind the 95 and repeat the process: 954 / 252

Moving on to step 7:
252 goes into 954 3 times with a remainder of 198.
Use 3 as the next digit of our solution. 
Result so far: 11403.0
Subtracting 756 from 954 leaves us with 198.
Include the next digit (0) from the dividend after 198, then repeat: 1980 / 252

Going ahead to step 8:
252 can be fit into 1980 7 times, resulting in a remainder of 216.
Use 7 as the next digit of our solution. 
Result so far: 114037.0
Deduct 1764 from 1980 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 9:
2160 divided by 252 is 8 with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 114037.8
Subtracting 2016 from 2160 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 10:
When dividing 1440 by 252, we get 5 with a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 114037.85
Deduct 1260 from 1440 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
The number 252 fits into 1800 7 times, leaving a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 114037.857
The remainder is 36 after subtracting 1764 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
The number 252 fits into 360 1 times, leaving a remainder of 108.
The next digit of our result is 1. 
Result so far: 114037.8571
Subtracting 252 from 360 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 13:
252 goes into 1080 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 114037.85714
Deduct 1008 from 1080 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
720 divided by 252 is 2 with a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 114037.857142
Subtracting 504 from 720 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 15:
252 goes into 2160 8 times with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 114037.8571428
Deduct 2016 from 2160 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 16:
When dividing 1440 by 252, we get 5 with a remainder of 180.
The next digit of our result is 5. 
Result so far: 114037.85714285
The remainder is 180 after subtracting 1260 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 114037.85714285 with a remaining 1.8e-07.
