We look at the division of 31199804 by 253 
The aim is to understand the frequency of 253 in 31199804.

Moving on to step 1:
253 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 253

Let's proceed to step 2:
If we divide 31 by 253, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 253

On to step 3:
253 goes into 311 1 times with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 253 from 311 to get 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 253

Moving on to step 4:
When dividing 589 by 253, we get 2 with a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 506 from 589 leaves us with 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 253

On to step 5:
253 goes into 839 3 times with a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtract 759 from 839 to get 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 253

Moving on to step 6:
The number 253 fits into 808 3 times, leaving a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 1233.0
Subtracting 759 from 808 leaves us with 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 253

Step 7:
If we divide 490 by 253, we get 1 and a remainder of 237.
Record the quotient 1 as the next digit in the result. 
Result so far: 12331.0
Subtract 253 from 490 to get 237.
Append the next digit (4) from the dividend to 237 and continue with: 2374 / 253

Moving on to step 8:
When dividing 2374 by 253, we get 9 with a remainder of 97.
Use 9 as the next digit of our solution. 
Result so far: 123319.0
If we subtract 2277 from 2374, we get 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 9:
253 can be fit into 970 3 times, resulting in a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 123319.3
Subtracting 759 from 970 leaves us 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.

Advancing to step 10:
2110 divided by 253 is 8 with a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 123319.38
The remainder is 86 after subtracting 2024 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
253 goes into 860 3 times with a remainder of 101.
The next digit of our result is 3. 
Result so far: 123319.383
Deduct 759 from 860 and we're left 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 12:
If we divide 1010 by 253, we get 3 and a remainder of 251.
Use 3 as the next digit of our solution. 
Result so far: 123319.3833
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 result is 123319.3833 with a remainder of 0.00251.
