12002450 divided by 253 
The aim is to understand the frequency of 253 in 12002450.

Moving on to step 1:
When dividing 1 by 253, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 253

Moving on to step 2:
253 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 253

Moving on to step 3:
The number 253 fits into 120 0 times, leaving a remainder of 120.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Take the next digit (0) from the dividend and append it to 120, then repeat: 1200 / 253

Going ahead to step 4:
The number 253 fits into 1200 4 times, leaving a remainder of 188.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 1012 from 1200 leaves us with 188.
Append the next digit (2) from the dividend to 188 and continue with: 1882 / 253

Advancing to step 5:
When dividing 1882 by 253, we get 7 with a remainder of 111.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 1771 from 1882 and we're left with 111.
Grab the next digit (4) from the dividend, add it to 111, then carry on: 1114 / 253

Moving on to step 6:
If we divide 1114 by 253, we get 4 and a remainder of 102.
Put 4 as the next digit of the answer. 
Result so far: 474.0
Subtract 1012 from 1114 to get 102.
Fetch the next digit (5) from the dividend, attach it to 102 and continue: 1025 / 253

Step 7:
253 goes into 1025 4 times with a remainder of 13.
The next digit of our result is 4. 
Result so far: 4744.0
Deduct 1012 from 1025 and we're left with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 253

Going ahead to step 8:
253 goes into 130 0 times with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 47440.0
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 9:
1300 divided by 253 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 47440.5
If we subtract 1265 from 1300, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
When dividing 350 by 253, we get 1 with a remainder of 97.
The number 1 becomes the next digit in our result. 
Result so far: 47440.51
If we take 253 away from 350, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 11:
If we divide 970 by 253, we get 3 and a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 47440.513
If we take 759 away from 970, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 12:
253 can be fit into 2110 8 times, resulting in a remainder of 86.
Write down 8 as next digit of the result. 
Result so far: 47440.5138
Subtracting 2024 from 2110 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 13:
253 can be fit into 860 3 times, resulting in a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 47440.51383
Subtracting 759 from 860 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 14:
If we divide 1010 by 253, we get 3 and a remainder of 251.
The next digit of our result is 3. 
Result so far: 47440.513833
Deduct 759 from 1010 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

The final outcome is 47440.513833, with a leftover of 2.51e-05.
