25319414 ÷ 839 
The aim is to understand the frequency of 839 in 25319414.

Let's proceed to step 1:
839 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 839

Step 2:
25 divided by 839 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 839

Advancing to step 3:
If we divide 253 by 839, we get 0 and a remainder of 253.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 253 to get 253.
Take the next digit (1) from the dividend and append it to 253, then repeat: 2531 / 839

Going ahead to step 4:
839 goes into 2531 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2517 away from 2531, we end up with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 839

Going ahead to step 5:
The number 839 fits into 149 0 times, leaving a remainder of 149.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 149 after subtracting 0 from 149.
Take the next digit (4) from the dividend and append it to 149, then repeat: 1494 / 839

Moving on to step 6:
839 goes into 1494 1 times with a remainder of 655.
Write down 1 as next digit of the result. 
Result so far: 301.0
The remainder is 655 after subtracting 839 from 1494.
Append the next digit (1) from the dividend to 655 and continue with: 6551 / 839

On to step 7:
839 can be fit into 6551 7 times, resulting in a remainder of 678.
Write down 7 as next digit of the result. 
Result so far: 3017.0
If we take 5873 away from 6551, we end up with 678.
Take the next digit (4) from the dividend and append it to 678, then repeat: 6784 / 839

Going ahead to step 8:
When dividing 6784 by 839, we get 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 30178.0
If we take 6712 away from 6784, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
If we divide 720 by 839, we get 0 and a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 30178.0
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 10:
7200 divided by 839 is 8 with a remainder of 488.
Record the quotient 8 as the next digit in the result. 
Result so far: 30178.08
Subtracting 6712 from 7200 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 11:
The number 839 fits into 4880 5 times, leaving a remainder of 685.
The number 5 becomes the next digit in our result. 
Result so far: 30178.085
Deduct 4195 from 4880 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 12:
The number 839 fits into 6850 8 times, leaving a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 30178.0858
If we take 6712 away from 6850, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 13:
The number 839 fits into 1380 1 times, leaving a remainder of 541.
The number 1 becomes the next digit in our result. 
Result so far: 30178.08581
If we subtract 839 from 1380, we get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 14:
When dividing 5410 by 839, we get 6 with a remainder of 376.
The next digit of our result is 6. 
Result so far: 30178.085816
If we take 5034 away from 5410, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 15:
The number 839 fits into 3760 4 times, leaving a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 30178.0858164
If we subtract 3356 from 3760, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 16:
The number 839 fits into 4040 4 times, leaving a remainder of 684.
Put 4 as the next digit of the answer. 
Result so far: 30178.08581644
The remainder is 684 after subtracting 3356 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

In conclusion, the division gives 30178.08581644 with a balance of 6.84e-07.
