We're dividing 25246301 by 857 
The aim is to understand the frequency of 857 in 25246301.

Going ahead to step 1:
2 divided by 857 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 857

Let's proceed to step 2:
The number 857 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 857

Step 3:
252 divided by 857 is 0 with a remainder of 252.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 252 and we're left with 252.
Take the next digit (4) from the dividend and append it to 252, then repeat: 2524 / 857

Advancing to step 4:
857 can be fit into 2524 2 times, resulting in a remainder of 810.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1714 from 2524 and we're left with 810.
Bring next digit (6) of the dividend behind the 810 and repeat the process: 8106 / 857

Advancing to step 5:
857 goes into 8106 9 times with a remainder of 393.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 7713 from 8106, we get 393.
Take the next digit (3) from the dividend and append it to 393, then repeat: 3933 / 857

On to step 6:
857 can be fit into 3933 4 times, resulting in a remainder of 505.
Put 4 as the next digit of the answer. 
Result so far: 294.0
Subtract 3428 from 3933 to get 505.
Fetch the next digit (0) from the dividend, attach it to 505 and continue: 5050 / 857

Moving on to step 7:
857 can be fit into 5050 5 times, resulting in a remainder of 765.
Write down 5 as next digit of the result. 
Result so far: 2945.0
If we subtract 4285 from 5050, we get 765.
Grab the next digit (1) from the dividend, add it to 765, then carry on: 7651 / 857

Advancing to step 8:
7651 divided by 857 is 8 with a remainder of 795.
Record the quotient 8 as the next digit in the result. 
Result so far: 29458.0
Subtracting 6856 from 7651 leaves us with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Going ahead to step 9:
The number 857 fits into 7950 9 times, leaving a remainder of 237.
The number 9 becomes the next digit in our result. 
Result so far: 29458.9
If we subtract 7713 from 7950, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 10:
2370 divided by 857 is 2 with a remainder of 656.
Write down 2 as next digit of the result. 
Result so far: 29458.92
Subtract 1714 from 2370 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Let's proceed to step 11:
857 goes into 6560 7 times with a remainder of 561.
The number 7 becomes the next digit in our result. 
Result so far: 29458.927
The remainder is 561 after subtracting 5999 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Going ahead to step 12:
857 can be fit into 5610 6 times, resulting in a remainder of 468.
The next digit of our result is 6. 
Result so far: 29458.9276
If we take 5142 away from 5610, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 13:
If we divide 4680 by 857, we get 5 and a remainder of 395.
Use 5 as the next digit of our solution. 
Result so far: 29458.92765
Subtract 4285 from 4680 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 14:
857 can be fit into 3950 4 times, resulting in a remainder of 522.
Put 4 as the next digit of the answer. 
Result so far: 29458.927654
If we subtract 3428 from 3950, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 15:
The number 857 fits into 5220 6 times, leaving a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 29458.9276546
Subtract 5142 from 5220 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 16:
780 divided by 857 is 0 with a remainder of 780.
Put 0 as the next digit of the answer. 
Result so far: 29458.9276546
Subtracting 0 from 780 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

In conclusion, the division gives 29458.9276546 with a balance of 7.8e-07.
