We divide 7924028 by 257
The aim is to understand the frequency of 257 in 7924028.

Going ahead to step 1:
The number 257 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 257

Moving on to step 2:
The number 257 fits into 79 0 times, leaving a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Take the next digit (2) from the dividend and append it to 79, then repeat: 792 / 257

Step 3:
792 divided by 257 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 771 away from 792, we end up with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 257

Step 4:
The number 257 fits into 214 0 times, leaving a remainder of 214.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 214 leaves us with 214.
Include the next digit (0) from the dividend after 214, then repeat: 2140 / 257

Step 5:
257 can be fit into 2140 8 times, resulting in a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 308.0
Subtract 2056 from 2140 to get 84.
Append the next digit (2) from the dividend to 84 and continue with: 842 / 257

On to step 6:
When dividing 842 by 257, we get 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 3083.0
If we subtract 771 from 842, we get 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 257

On to step 7:
257 can be fit into 718 2 times, resulting in a remainder of 204.
The next digit of our result is 2. 
Result so far: 30832.0
Subtract 514 from 718 to get 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 8:
When dividing 2040 by 257, we get 7 with a remainder of 241.
Write down 7 as next digit of the result. 
Result so far: 30832.7
Deduct 1799 from 2040 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 9:
257 goes into 2410 9 times with a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 30832.79
If we take 2313 away from 2410, 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.

Step 10:
When dividing 970 by 257, we get 3 with a remainder of 199.
Write down 3 as next digit of the result. 
Result so far: 30832.793
Subtract 771 from 970 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 11:
257 can be fit into 1990 7 times, resulting in a remainder of 191.
The number 7 becomes the next digit in our result. 
Result so far: 30832.7937
Subtract 1799 from 1990 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 12:
When dividing 1910 by 257, we get 7 with a remainder of 111.
Write down 7 as next digit of the result. 
Result so far: 30832.79377
Deduct 1799 from 1910 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

The final result is 30832.79377 with a remainder of 0.000111.
