We're dividing 30575855 by 257 
The aim is to understand the frequency of 257 in 30575855.

On to step 1:
257 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 257

Going ahead to step 2:
When dividing 30 by 257, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 257

Moving on to step 3:
If we divide 305 by 257, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 257 from 305 and we're left with 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 257

Going ahead to step 4:
The number 257 fits into 487 1 times, leaving a remainder of 230.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 257 from 487 leaves us with 230.
Fetch the next digit (5) from the dividend, attach it to 230 and continue: 2305 / 257

Let's proceed to step 5:
2305 divided by 257 is 8 with a remainder of 249.
The next digit of our result is 8. 
Result so far: 118.0
If we subtract 2056 from 2305, we get 249.
Append the next digit (8) from the dividend to 249 and continue with: 2498 / 257

On to step 6:
257 can be fit into 2498 9 times, resulting in a remainder of 185.
Write down 9 as next digit of the result. 
Result so far: 1189.0
If we subtract 2313 from 2498, we get 185.
Fetch the next digit (5) from the dividend, attach it to 185 and continue: 1855 / 257

Step 7:
257 can be fit into 1855 7 times, resulting in a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 11897.0
If we subtract 1799 from 1855, we get 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 257

Advancing to step 8:
If we divide 565 by 257, we get 2 and a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 118972.0
The remainder is 51 after subtracting 514 from 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
If we divide 510 by 257, we get 1 and a remainder of 253.
The next digit of our result is 1. 
Result so far: 118972.1
Subtracting 257 from 510 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 10:
2530 divided by 257 is 9 with a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 118972.19
If we subtract 2313 from 2530, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 11:
257 can be fit into 2170 8 times, resulting in a remainder of 114.
Record the quotient 8 as the next digit in the result. 
Result so far: 118972.198
Deduct 2056 from 2170 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 12:
When dividing 1140 by 257, we get 4 with a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 118972.1984
If we take 1028 away from 1140, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 13:
If we divide 1120 by 257, we get 4 and a remainder of 92.
Record the quotient 4 as the next digit in the result. 
Result so far: 118972.19844
Subtracting 1028 from 1120 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 118972.19844 with a remaining 9.2e-05.
