54739139 ÷ 252 
The aim is to understand the frequency of 252 in 54739139.

On to step 1:
5 divided by 252 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 252

On to step 2:
When dividing 54 by 252, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (7) from the dividend and append it to 54, then repeat: 547 / 252

On to step 3:
When dividing 547 by 252, we get 2 with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 43 after subtracting 504 from 547.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 252

Let's proceed to step 4:
If we divide 433 by 252, we get 1 and a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 181 after subtracting 252 from 433.
Include the next digit (9) from the dividend after 181, then repeat: 1819 / 252

Advancing to step 5:
252 can be fit into 1819 7 times, resulting in a remainder of 55.
The next digit of our result is 7. 
Result so far: 217.0
The remainder is 55 after subtracting 1764 from 1819.
Fetch the next digit (1) from the dividend, attach it to 55 and continue: 551 / 252

Step 6:
551 divided by 252 is 2 with a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 2172.0
If we subtract 504 from 551, we get 47.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 252

Moving on to step 7:
When dividing 473 by 252, we get 1 with a remainder of 221.
The next digit of our result is 1. 
Result so far: 21721.0
Subtracting 252 from 473 leaves us with 221.
Grab the next digit (9) from the dividend, add it to 221, then carry on: 2219 / 252

Step 8:
2219 divided by 252 is 8 with a remainder of 203.
The number 8 becomes the next digit in our result. 
Result so far: 217218.0
Deduct 2016 from 2219 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 9:
2030 divided by 252 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 217218.8
The remainder is 14 after subtracting 2016 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
252 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 217218.8
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
If we divide 1400 by 252, we get 5 and a remainder of 140.
The next digit of our result is 5. 
Result so far: 217218.805
Subtract 1260 from 1400 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
252 can be fit into 1400 5 times, resulting in a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 217218.8055
Subtract 1260 from 1400 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 217218.8055 with a remainder of 0.0014.
