54277202 ÷ 257 
The aim is to understand the frequency of 257 in 54277202.

On to step 1:
The number 257 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 257

Step 2:
The number 257 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 257

Step 3:
The number 257 fits into 542 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 514 away from 542, we end up with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 257

On to step 4:
The number 257 fits into 287 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 257 from 287 to get 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 257

Going ahead to step 5:
307 divided by 257 is 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 211.0
If we subtract 257 from 307, we get 50.
Fetch the next digit (2) from the dividend, attach it to 50 and continue: 502 / 257

Going ahead to step 6:
If we divide 502 by 257, we get 1 and a remainder of 245.
Use 1 as the next digit of our solution. 
Result so far: 2111.0
Subtract 257 from 502 to get 245.
Fetch the next digit (0) from the dividend, attach it to 245 and continue: 2450 / 257

Moving on to step 7:
257 can be fit into 2450 9 times, resulting in a remainder of 137.
The number 9 becomes the next digit in our result. 
Result so far: 21119.0
The remainder is 137 after subtracting 2313 from 2450.
Append the next digit (2) from the dividend to 137 and continue with: 1372 / 257

Step 8:
257 goes into 1372 5 times with a remainder of 87.
Put 5 as the next digit of the answer. 
Result so far: 211195.0
If we subtract 1285 from 1372, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 9:
257 goes into 870 3 times with a remainder of 99.
The next digit of our result is 3. 
Result so far: 211195.3
If we subtract 771 from 870, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 10:
If we divide 990 by 257, we get 3 and a remainder of 219.
The next digit of our result is 3. 
Result so far: 211195.33
If we take 771 away from 990, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

After the division, we end up with 211195.33 and a remainder of 0.219.
