65488574 ÷ 257 
The aim is to understand the frequency of 257 in 65488574.

Step 1:
257 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 257

Let's proceed to step 2:
If we divide 65 by 257, we get 0 and a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 257

Let's proceed to step 3:
257 goes into 654 2 times with a remainder of 140.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 514 from 654 leaves us with 140.
Bring next digit (8) of the dividend behind the 140 and repeat the process: 1408 / 257

Let's proceed to step 4:
257 goes into 1408 5 times with a remainder of 123.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 1285 from 1408, we get 123.
Include the next digit (8) from the dividend after 123, then repeat: 1238 / 257

Going ahead to step 5:
257 can be fit into 1238 4 times, resulting in a remainder of 210.
Write down 4 as next digit of the result. 
Result so far: 254.0
Deduct 1028 from 1238 and we're left with 210.
Append the next digit (5) from the dividend to 210 and continue with: 2105 / 257

Step 6:
When dividing 2105 by 257, we get 8 with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 2548.0
If we subtract 2056 from 2105, we get 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 257

Advancing to step 7:
497 divided by 257 is 1 with a remainder of 240.
Write down 1 as next digit of the result. 
Result so far: 25481.0
Subtract 257 from 497 to get 240.
Take the next digit (4) from the dividend and append it to 240, then repeat: 2404 / 257

Step 8:
When dividing 2404 by 257, we get 9 with a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 254819.0
Subtract 2313 from 2404 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
257 goes into 910 3 times with a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 254819.3
Deduct 771 from 910 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 10:
If we divide 1390 by 257, we get 5 and a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 254819.35
The remainder is 105 after subtracting 1285 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 11:
If we divide 1050 by 257, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 254819.354
If we take 1028 away from 1050, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
When dividing 220 by 257, we get 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 254819.354
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 13:
257 can be fit into 2200 8 times, resulting in a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 254819.35408
If we take 2056 away from 2200, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 14:
1440 divided by 257 is 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 254819.354085
The remainder is 155 after subtracting 1285 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 15:
If we divide 1550 by 257, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 254819.3540856
Subtracting 1542 from 1550 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
If we divide 80 by 257, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 254819.3540856
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 254819.3540856 with a remaining 8e-08.
