We're dividing 95877847 by 257 
The aim is to understand the frequency of 257 in 95877847.

Let's proceed to step 1:
If we divide 9 by 257, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 257

Moving on to step 2:
If we divide 95 by 257, we get 0 and a remainder of 95.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 95 leaves us with 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 257

Moving on to step 3:
The number 257 fits into 958 3 times, leaving a remainder of 187.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 771 from 958, we get 187.
Include the next digit (7) from the dividend after 187, then repeat: 1877 / 257

Step 4:
The number 257 fits into 1877 7 times, leaving a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 1799 away from 1877, we end up with 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 257

Moving on to step 5:
The number 257 fits into 787 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 373.0
Deduct 771 from 787 and we're left with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 257

Advancing to step 6:
When dividing 168 by 257, we get 0 with a remainder of 168.
Record the quotient 0 as the next digit in the result. 
Result so far: 3730.0
Subtracting 0 from 168 leaves us with 168.
Bring next digit (4) of the dividend behind the 168 and repeat the process: 1684 / 257

On to step 7:
If we divide 1684 by 257, we get 6 and a remainder of 142.
The number 6 becomes the next digit in our result. 
Result so far: 37306.0
If we subtract 1542 from 1684, we get 142.
Take the next digit (7) from the dividend and append it to 142, then repeat: 1427 / 257

Advancing to step 8:
The number 257 fits into 1427 5 times, leaving a remainder of 142.
The number 5 becomes the next digit in our result. 
Result so far: 373065.0
Subtracting 1285 from 1427 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 9:
If we divide 1420 by 257, we get 5 and a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 373065.5
Deduct 1285 from 1420 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 10:
257 goes into 1350 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 373065.55
Subtracting 1285 from 1350 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 373065.55 with a remainder of 0.065.
