We look at the division of 54167899 by 252 
The aim is to understand the frequency of 252 in 54167899.

Moving on to step 1:
If we divide 5 by 252, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 252

Going ahead to step 2:
When dividing 54 by 252, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 252

Moving on to step 3:
252 can be fit into 541 2 times, resulting in a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 504 from 541 leaves us with 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 252

Let's proceed to step 4:
When dividing 376 by 252, we get 1 with a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 252 away from 376, we end up with 124.
Append the next digit (7) from the dividend to 124 and continue with: 1247 / 252

Let's proceed to step 5:
The number 252 fits into 1247 4 times, leaving a remainder of 239.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
The remainder is 239 after subtracting 1008 from 1247.
Grab the next digit (8) from the dividend, add it to 239, then carry on: 2398 / 252

Going ahead to step 6:
252 goes into 2398 9 times with a remainder of 130.
Put 9 as the next digit of the answer. 
Result so far: 2149.0
Deduct 2268 from 2398 and we're left with 130.
Take the next digit (9) from the dividend and append it to 130, then repeat: 1309 / 252

Step 7:
If we divide 1309 by 252, we get 5 and a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 21495.0
If we take 1260 away from 1309, we end up with 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 252

Advancing to step 8:
252 can be fit into 499 1 times, resulting in a remainder of 247.
Write down 1 as next digit of the result. 
Result so far: 214951.0
Subtracting 252 from 499 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 9:
The number 252 fits into 2470 9 times, leaving a remainder of 202.
The number 9 becomes the next digit in our result. 
Result so far: 214951.9
The remainder is 202 after subtracting 2268 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 10:
252 goes into 2020 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 214951.98
Subtract 2016 from 2020 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
When dividing 40 by 252, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 214951.98
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 252 is 1 with a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 214951.9801
If we subtract 252 from 400, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 13:
1480 divided by 252 is 5 with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 214951.98015
Deduct 1260 from 1480 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
252 can be fit into 2200 8 times, resulting in a remainder of 184.
The next digit of our result is 8. 
Result so far: 214951.980158
Subtracting 2016 from 2200 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 15:
252 can be fit into 1840 7 times, resulting in a remainder of 76.
The next digit of our result is 7. 
Result so far: 214951.9801587
The remainder is 76 after subtracting 1764 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 16:
If we divide 760 by 252, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 214951.98015873
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 214951.98015873 and a remainder of 4e-09.
