2687318 ÷ 257 
The aim is to understand the frequency of 257 in 2687318.

Let's proceed to step 1:
When dividing 2 by 257, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 257

Going ahead to step 2:
26 divided by 257 is 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 257

Going ahead to step 3:
The number 257 fits into 268 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 257 from 268 and we're left with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 257

On to step 4:
257 goes into 117 0 times with a remainder of 117.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 117 after subtracting 0 from 117.
Grab the next digit (3) from the dividend, add it to 117, then carry on: 1173 / 257

Moving on to step 5:
257 can be fit into 1173 4 times, resulting in a remainder of 145.
Write down 4 as next digit of the result. 
Result so far: 104.0
Deduct 1028 from 1173 and we're left with 145.
Fetch the next digit (1) from the dividend, attach it to 145 and continue: 1451 / 257

Step 6:
When dividing 1451 by 257, we get 5 with a remainder of 166.
Put 5 as the next digit of the answer. 
Result so far: 1045.0
Subtracting 1285 from 1451 leaves us with 166.
Bring next digit (8) of the dividend behind the 166 and repeat the process: 1668 / 257

On to step 7:
When dividing 1668 by 257, we get 6 with a remainder of 126.
The number 6 becomes the next digit in our result. 
Result so far: 10456.0
If we take 1542 away from 1668, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 8:
When dividing 1260 by 257, we get 4 with a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 10456.4
The remainder is 232 after subtracting 1028 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 9:
The number 257 fits into 2320 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 10456.49
Subtract 2313 from 2320 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
257 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 10456.49
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
If we divide 700 by 257, we get 2 and a remainder of 186.
The next digit of our result is 2. 
Result so far: 10456.4902
Subtract 514 from 700 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 12:
1860 divided by 257 is 7 with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 10456.49027
Subtracting 1799 from 1860 leaves us with 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 13:
When dividing 610 by 257, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 10456.490272
Deduct 514 from 610 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
If we divide 960 by 257, we get 3 and a remainder of 189.
Record the quotient 3 as the next digit in the result. 
Result so far: 10456.4902723
The remainder is 189 after subtracting 771 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 15:
257 can be fit into 1890 7 times, resulting in a remainder of 91.
Record the quotient 7 as the next digit in the result. 
Result so far: 10456.49027237
Subtracting 1799 from 1890 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

In conclusion, the division gives 10456.49027237 with a balance of 9.1e-08.
