12479771 divided by 257 
The aim is to understand the frequency of 257 in 12479771.

Moving on to step 1:
257 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 257

Advancing to step 2:
12 divided by 257 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 257

Going ahead to step 3:
124 divided by 257 is 0 with a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 124 to get 124.
Take the next digit (7) from the dividend and append it to 124, then repeat: 1247 / 257

Step 4:
The number 257 fits into 1247 4 times, leaving a remainder of 219.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1028 from 1247, we get 219.
Take the next digit (9) from the dividend and append it to 219, then repeat: 2199 / 257

On to step 5:
257 can be fit into 2199 8 times, resulting in a remainder of 143.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we subtract 2056 from 2199, we get 143.
Bring next digit (7) of the dividend behind the 143 and repeat the process: 1437 / 257

Going ahead to step 6:
When dividing 1437 by 257, we get 5 with a remainder of 152.
The number 5 becomes the next digit in our result. 
Result so far: 485.0
Subtract 1285 from 1437 to get 152.
Grab the next digit (7) from the dividend, add it to 152, then carry on: 1527 / 257

Step 7:
257 can be fit into 1527 5 times, resulting in a remainder of 242.
The next digit of our result is 5. 
Result so far: 4855.0
The remainder is 242 after subtracting 1285 from 1527.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 257

Advancing to step 8:
257 goes into 2421 9 times with a remainder of 108.
The number 9 becomes the next digit in our result. 
Result so far: 48559.0
Subtract 2313 from 2421 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 9:
257 goes into 1080 4 times with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 48559.4
Subtract 1028 from 1080 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
257 goes into 520 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 48559.42
If we subtract 514 from 520, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 257 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 48559.42
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
When dividing 600 by 257, we get 2 with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 48559.4202
If we take 514 away from 600, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 13:
The number 257 fits into 860 3 times, leaving a remainder of 89.
Use 3 as the next digit of our solution. 
Result so far: 48559.42023
If we take 771 away from 860, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 14:
257 goes into 890 3 times with a remainder of 119.
Record the quotient 3 as the next digit in the result. 
Result so far: 48559.420233
The remainder is 119 after subtracting 771 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

The final outcome is 48559.420233, with a leftover of 1.19e-05.
