Let's divide 31143266 by 253
The aim is to understand the frequency of 253 in 31143266.

Moving on to step 1:
253 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 253

Advancing to step 2:
31 divided by 253 is 0 with 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.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 253

Step 3:
If we divide 311 by 253, we get 1 and a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 253 from 311 to get 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 253

On to step 4:
If we divide 584 by 253, we get 2 and a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 506 from 584 and we're left with 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 253

On to step 5:
The number 253 fits into 783 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we take 759 away from 783, we end up with 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 253

Advancing to step 6:
242 divided by 253 is 0 with a remainder of 242.
Write down 0 as next digit of the result. 
Result so far: 1230.0
The remainder is 242 after subtracting 0 from 242.
Fetch the next digit (6) from the dividend, attach it to 242 and continue: 2426 / 253

Step 7:
When dividing 2426 by 253, we get 9 with a remainder of 149.
Record the quotient 9 as the next digit in the result. 
Result so far: 12309.0
The remainder is 149 after subtracting 2277 from 2426.
Include the next digit (6) from the dividend after 149, then repeat: 1496 / 253

Step 8:
If we divide 1496 by 253, we get 5 and a remainder of 231.
Put 5 as the next digit of the answer. 
Result so far: 123095.0
If we subtract 1265 from 1496, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 9:
When dividing 2310 by 253, we get 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 123095.9
Subtract 2277 from 2310 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
253 goes into 330 1 times with a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 123095.91
If we subtract 253 from 330, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
The number 253 fits into 770 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 123095.913
Deduct 759 from 770 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
The number 253 fits into 110 0 times, leaving a remainder of 110.
The next digit of our result is 0. 
Result so far: 123095.913
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 13:
253 can be fit into 1100 4 times, resulting in a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 123095.91304
If we take 1012 away from 1100, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 14:
When dividing 880 by 253, we get 3 with a remainder of 121.
The next digit of our result is 3. 
Result so far: 123095.913043
The remainder is 121 after subtracting 759 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 15:
253 can be fit into 1210 4 times, resulting in a remainder of 198.
Use 4 as the next digit of our solution. 
Result so far: 123095.9130434
Deduct 1012 from 1210 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 16:
When dividing 1980 by 253, we get 7 with a remainder of 209.
The next digit of our result is 7. 
Result so far: 123095.91304347
Subtracting 1771 from 1980 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

The final result is 123095.91304347 with a remainder of 2.09e-07.
