90203672 ÷ 252 
The aim is to understand the frequency of 252 in 90203672.

Going ahead to step 1:
252 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 252

Moving on to step 2:
90 divided by 252 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 252

Step 3:
If we divide 902 by 252, we get 3 and a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 756 from 902 to get 146.
Include the next digit (0) from the dividend after 146, then repeat: 1460 / 252

Advancing to step 4:
252 goes into 1460 5 times with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 1260 from 1460 and we're left with 200.
Include the next digit (3) from the dividend after 200, then repeat: 2003 / 252

Let's proceed to step 5:
252 can be fit into 2003 7 times, resulting in a remainder of 239.
Record the quotient 7 as the next digit in the result. 
Result so far: 357.0
If we subtract 1764 from 2003, we get 239.
Append the next digit (6) from the dividend to 239 and continue with: 2396 / 252

Moving on to step 6:
When dividing 2396 by 252, we get 9 with a remainder of 128.
Put 9 as the next digit of the answer. 
Result so far: 3579.0
Subtract 2268 from 2396 to get 128.
Bring next digit (7) of the dividend behind the 128 and repeat the process: 1287 / 252

Moving on to step 7:
The number 252 fits into 1287 5 times, leaving a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 35795.0
If we subtract 1260 from 1287, we get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 252

Advancing to step 8:
The number 252 fits into 272 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 357951.0
Subtract 252 from 272 to get 20.
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 9:
If we divide 200 by 252, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 357951.0
If we take 0 away from 200, we end up with 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 10:
252 goes into 2000 7 times with a remainder of 236.
Write down 7 as next digit of the result. 
Result so far: 357951.07
If we subtract 1764 from 2000, we get 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 11:
The number 252 fits into 2360 9 times, leaving a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 357951.079
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.

Step 12:
252 can be fit into 920 3 times, resulting in a remainder of 164.
Record the quotient 3 as the next digit in the result. 
Result so far: 357951.0793
If we subtract 756 from 920, we 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.

On to step 13:
If we divide 1640 by 252, we get 6 and a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 357951.07936
If we subtract 1512 from 1640, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 14:
252 can be fit into 1280 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 357951.079365
Subtracting 1260 from 1280 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
252 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 357951.079365
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.

Step 16:
2000 divided by 252 is 7 with a remainder of 236.
Use 7 as the next digit of our solution. 
Result so far: 357951.07936507
If we subtract 1764 from 2000, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The quotient of the division is 357951.07936507, and the remainder is 2.36e-07.
