We divide 67847484 by 257
The aim is to understand the frequency of 257 in 67847484.

Advancing to step 1:
If we divide 6 by 257, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 257

Moving on to step 2:
67 divided by 257 is 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 257

Step 3:
257 goes into 678 2 times with a remainder of 164.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 514 from 678 and we're left with 164.
Grab the next digit (4) from the dividend, add it to 164, then carry on: 1644 / 257

Advancing to step 4:
257 goes into 1644 6 times with a remainder of 102.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 102 after subtracting 1542 from 1644.
Fetch the next digit (7) from the dividend, attach it to 102 and continue: 1027 / 257

Going ahead to step 5:
The number 257 fits into 1027 3 times, leaving a remainder of 256.
The next digit of our result is 3. 
Result so far: 263.0
Deduct 771 from 1027 and we're left with 256.
Include the next digit (4) from the dividend after 256, then repeat: 2564 / 257

Advancing to step 6:
257 can be fit into 2564 9 times, resulting in a remainder of 251.
Use 9 as the next digit of our solution. 
Result so far: 2639.0
Deduct 2313 from 2564 and we're left with 251.
Append the next digit (8) from the dividend to 251 and continue with: 2518 / 257

Let's proceed to step 7:
When dividing 2518 by 257, we get 9 with a remainder of 205.
The next digit of our result is 9. 
Result so far: 26399.0
Subtracting 2313 from 2518 leaves us with 205.
Fetch the next digit (4) from the dividend, attach it to 205 and continue: 2054 / 257

Going ahead to step 8:
257 can be fit into 2054 7 times, resulting in a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 263997.0
If we take 1799 away from 2054, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 9:
257 can be fit into 2550 9 times, resulting in a remainder of 237.
Put 9 as the next digit of the answer. 
Result so far: 263997.9
Subtract 2313 from 2550 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 10:
257 can be fit into 2370 9 times, resulting in a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 263997.99
Subtract 2313 from 2370 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 263997.99, with a leftover of 0.057.
