We look at the division of 87779396 by 252 
The aim is to understand the frequency of 252 in 87779396.

Step 1:
8 divided by 252 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 252

Advancing to step 2:
87 divided by 252 is 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 252

On to step 3:
The number 252 fits into 877 3 times, leaving a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 756 from 877 and we're left with 121.
Grab the next digit (7) from the dividend, add it to 121, then carry on: 1217 / 252

Step 4:
When dividing 1217 by 252, we get 4 with a remainder of 209.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtract 1008 from 1217 to get 209.
Include the next digit (9) from the dividend after 209, then repeat: 2099 / 252

Let's proceed to step 5:
2099 divided by 252 is 8 with a remainder of 83.
Use 8 as the next digit of our solution. 
Result so far: 348.0
Subtracting 2016 from 2099 leaves us with 83.
Include the next digit (3) from the dividend after 83, then repeat: 833 / 252

Moving on to step 6:
252 can be fit into 833 3 times, resulting in a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 3483.0
If we take 756 away from 833, we end up with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 252

Step 7:
If we divide 779 by 252, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 34833.0
The remainder is 23 after subtracting 756 from 779.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 252

Going ahead to step 8:
If we divide 236 by 252, we get 0 and a remainder of 236.
Use 0 as the next digit of our solution. 
Result so far: 348330.0
If we take 0 away from 236, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 9:
When dividing 2360 by 252, we get 9 with a remainder of 92.
Record the quotient 9 as the next digit in the result. 
Result so far: 348330.9
Subtracting 2268 from 2360 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
When dividing 920 by 252, we get 3 with a remainder of 164.
Record the quotient 3 as the next digit in the result. 
Result so far: 348330.93
If we take 756 away from 920, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 11:
If we divide 1640 by 252, we get 6 and a remainder of 128.
The next digit of our result is 6. 
Result so far: 348330.936
Subtracting 1512 from 1640 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
252 goes into 1280 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 348330.9365
The remainder is 20 after subtracting 1260 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
200 divided by 252 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 348330.9365
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
252 can be fit into 2000 7 times, resulting in a remainder of 236.
The number 7 becomes the next digit in our result. 
Result so far: 348330.936507
If we take 1764 away from 2000, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 15:
When dividing 2360 by 252, we get 9 with a remainder of 92.
Write down 9 as next digit of the result. 
Result so far: 348330.9365079
If we subtract 2268 from 2360, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 16:
252 goes into 920 3 times with a remainder of 164.
The number 3 becomes the next digit in our result. 
Result so far: 348330.93650793
Subtract 756 from 920 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Our division results in 348330.93650793 with a remaining 1.64e-07.
