We're dividing 75073008 by 253 
The aim is to understand the frequency of 253 in 75073008.

Let's proceed to step 1:
The number 253 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 253

Step 2:
If we divide 75 by 253, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 253

Advancing to step 3:
253 can be fit into 750 2 times, resulting in a remainder of 244.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 506 from 750 leaves us with 244.
Include the next digit (7) from the dividend after 244, then repeat: 2447 / 253

On to step 4:
If we divide 2447 by 253, we get 9 and a remainder of 170.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 2277 from 2447 leaves us with 170.
Append the next digit (3) from the dividend to 170 and continue with: 1703 / 253

On to step 5:
253 goes into 1703 6 times with a remainder of 185.
Use 6 as the next digit of our solution. 
Result so far: 296.0
If we subtract 1518 from 1703, we get 185.
Fetch the next digit (0) from the dividend, attach it to 185 and continue: 1850 / 253

On to step 6:
1850 divided by 253 is 7 with a remainder of 79.
The next digit of our result is 7. 
Result so far: 2967.0
If we take 1771 away from 1850, we end up with 79.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 253

On to step 7:
When dividing 790 by 253, we get 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 29673.0
Subtracting 759 from 790 leaves us with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 253

Step 8:
If we divide 318 by 253, we get 1 and a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 296731.0
Deduct 253 from 318 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 9:
If we divide 650 by 253, we get 2 and a remainder of 144.
The next digit of our result is 2. 
Result so far: 296731.2
The remainder is 144 after subtracting 506 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 10:
1440 divided by 253 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 296731.25
Subtract 1265 from 1440 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 11:
The number 253 fits into 1750 6 times, leaving a remainder of 232.
Use 6 as the next digit of our solution. 
Result so far: 296731.256
If we take 1518 away from 1750, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 12:
If we divide 2320 by 253, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 296731.2569
If we take 2277 away from 2320, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
If we divide 430 by 253, we get 1 and a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 296731.25691
If we take 253 away from 430, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 14:
The number 253 fits into 1770 6 times, leaving a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 296731.256916
If we subtract 1518 from 1770, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 15:
The number 253 fits into 2520 9 times, leaving a remainder of 243.
Use 9 as the next digit of our solution. 
Result so far: 296731.2569169
If we take 2277 away from 2520, we end up with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Moving on to step 16:
253 goes into 2430 9 times with a remainder of 153.
Use 9 as the next digit of our solution. 
Result so far: 296731.25691699
If we subtract 2277 from 2430, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The quotient of the division is 296731.25691699, and the remainder is 1.53e-07.
