Let's divide 42130717 by 257
The aim is to understand the frequency of 257 in 42130717.

Let's proceed to step 1:
When dividing 4 by 257, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 257

Let's proceed to step 2:
When dividing 42 by 257, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 257

Step 3:
421 divided by 257 is 1 with a remainder of 164.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 257 from 421, we get 164.
Take the next digit (3) from the dividend and append it to 164, then repeat: 1643 / 257

Going ahead to step 4:
257 goes into 1643 6 times with a remainder of 101.
The next digit of our result is 6. 
Result so far: 16.0
If we take 1542 away from 1643, we end up with 101.
Grab the next digit (0) from the dividend, add it to 101, then carry on: 1010 / 257

Moving on to step 5:
257 can be fit into 1010 3 times, resulting in a remainder of 239.
Write down 3 as next digit of the result. 
Result so far: 163.0
Deduct 771 from 1010 and we're left with 239.
Include the next digit (7) from the dividend after 239, then repeat: 2397 / 257

On to step 6:
2397 divided by 257 is 9 with a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 1639.0
Subtracting 2313 from 2397 leaves us with 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 257

On to step 7:
When dividing 841 by 257, we get 3 with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 16393.0
Subtract 771 from 841 to get 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 257

On to step 8:
707 divided by 257 is 2 with a remainder of 193.
The next digit of our result is 2. 
Result so far: 163932.0
Subtract 514 from 707 to get 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 9:
1930 divided by 257 is 7 with a remainder of 131.
Put 7 as the next digit of the answer. 
Result so far: 163932.7
The remainder is 131 after subtracting 1799 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 10:
When dividing 1310 by 257, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 163932.75
Subtract 1285 from 1310 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
When dividing 250 by 257, we get 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 163932.75
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
The number 257 fits into 2500 9 times, leaving a remainder of 187.
The number 9 becomes the next digit in our result. 
Result so far: 163932.7509
Subtracting 2313 from 2500 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 13:
If we divide 1870 by 257, we get 7 and a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 163932.75097
Subtracting 1799 from 1870 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
If we divide 710 by 257, we get 2 and a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 163932.750972
If we subtract 514 from 710, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 15:
If we divide 1960 by 257, we get 7 and a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 163932.7509727
Subtract 1799 from 1960 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 16:
257 can be fit into 1610 6 times, resulting in a remainder of 68.
The next digit of our result is 6. 
Result so far: 163932.75097276
Subtract 1542 from 1610 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 163932.75097276 with a remainder of 6.8e-08.
