We look at the division of 65267763 by 257 
The aim is to understand the frequency of 257 in 65267763.

On to step 1:
When dividing 6 by 257, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 257

Step 2:
257 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 257

Advancing to step 3:
When dividing 652 by 257, we get 2 with a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 514 from 652 leaves us with 138.
Bring next digit (6) of the dividend behind the 138 and repeat the process: 1386 / 257

On to step 4:
1386 divided by 257 is 5 with a remainder of 101.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 1285 from 1386, we get 101.
Take the next digit (7) from the dividend and append it to 101, then repeat: 1017 / 257

Let's proceed to step 5:
When dividing 1017 by 257, we get 3 with a remainder of 246.
The next digit of our result is 3. 
Result so far: 253.0
If we take 771 away from 1017, we end up with 246.
Include the next digit (7) from the dividend after 246, then repeat: 2467 / 257

Going ahead to step 6:
2467 divided by 257 is 9 with a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 2539.0
Deduct 2313 from 2467 and we're left with 154.
Grab the next digit (6) from the dividend, add it to 154, then carry on: 1546 / 257

Step 7:
If we divide 1546 by 257, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 25396.0
If we subtract 1542 from 1546, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 257

On to step 8:
When dividing 43 by 257, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 253960.0
The remainder is 43 after subtracting 0 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
The number 257 fits into 430 1 times, leaving a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 253960.1
If we subtract 257 from 430, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 10:
If we divide 1730 by 257, we get 6 and a remainder of 188.
Put 6 as the next digit of the answer. 
Result so far: 253960.16
Subtract 1542 from 1730 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
257 goes into 1880 7 times with a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 253960.167
Subtracting 1799 from 1880 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 12:
If we divide 810 by 257, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 253960.1673
If we subtract 771 from 810, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
257 goes into 390 1 times with a remainder of 133.
Write down 1 as next digit of the result. 
Result so far: 253960.16731
Subtracting 257 from 390 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 14:
If we divide 1330 by 257, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 253960.167315
If we take 1285 away from 1330, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 15:
If we divide 450 by 257, we get 1 and a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 253960.1673151
If we take 257 away from 450, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 16:
257 goes into 1930 7 times with a remainder of 131.
Put 7 as the next digit of the answer. 
Result so far: 253960.16731517
If we take 1799 away from 1930, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The final result is 253960.16731517 with a remainder of 1.31e-07.
