We look at the division of 50256003 by 253 
The aim is to understand the frequency of 253 in 50256003.

Moving on to step 1:
If we divide 5 by 253, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 253

On to step 2:
50 divided by 253 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 253

On to step 3:
502 divided by 253 is 1 with a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 253 from 502, we get 249.
Include the next digit (5) from the dividend after 249, then repeat: 2495 / 253

Let's proceed to step 4:
When dividing 2495 by 253, we get 9 with a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 2277 from 2495 to get 218.
Bring next digit (6) of the dividend behind the 218 and repeat the process: 2186 / 253

Advancing to step 5:
253 can be fit into 2186 8 times, resulting in a remainder of 162.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
Subtract 2024 from 2186 to get 162.
Fetch the next digit (0) from the dividend, attach it to 162 and continue: 1620 / 253

Step 6:
253 goes into 1620 6 times with a remainder of 102.
Write down 6 as next digit of the result. 
Result so far: 1986.0
Subtract 1518 from 1620 to get 102.
Include the next digit (0) from the dividend after 102, then repeat: 1020 / 253

Going ahead to step 7:
253 can be fit into 1020 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 19864.0
Subtract 1012 from 1020 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 253

Moving on to step 8:
253 goes into 83 0 times with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 198640.0
If we take 0 away from 83, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
If we divide 830 by 253, we get 3 and a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 198640.3
The remainder is 71 after subtracting 759 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
253 can be fit into 710 2 times, resulting in a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 198640.32
Deduct 506 from 710 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 11:
253 can be fit into 2040 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 198640.328
The remainder is 16 after subtracting 2024 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
The number 253 fits into 160 0 times, leaving a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 198640.328
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
253 goes into 1600 6 times with a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 198640.32806
If we take 1518 away from 1600, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 14:
The number 253 fits into 820 3 times, leaving a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 198640.328063
If we subtract 759 from 820, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 15:
610 divided by 253 is 2 with a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 198640.3280632
Subtracting 506 from 610 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 16:
When dividing 1040 by 253, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 198640.32806324
Deduct 1012 from 1040 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 198640.32806324 with a balance of 2.8e-08.
