We're dividing 1439012 by 912 
The aim is to understand the frequency of 912 in 1439012.

Going ahead to step 1:
1 divided by 912 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 912

Let's proceed to step 2:
912 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 912

Advancing to step 3:
If we divide 143 by 912, we get 0 and a remainder of 143.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 143 leaves us with 143.
Take the next digit (9) from the dividend and append it to 143, then repeat: 1439 / 912

On to step 4:
If we divide 1439 by 912, we get 1 and a remainder of 527.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 527 after subtracting 912 from 1439.
Fetch the next digit (0) from the dividend, attach it to 527 and continue: 5270 / 912

Let's proceed to step 5:
912 can be fit into 5270 5 times, resulting in a remainder of 710.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 4560 from 5270, we get 710.
Bring next digit (1) of the dividend behind the 710 and repeat the process: 7101 / 912

Let's proceed to step 6:
912 goes into 7101 7 times with a remainder of 717.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
Subtract 6384 from 7101 to get 717.
Bring next digit (2) of the dividend behind the 717 and repeat the process: 7172 / 912

Going ahead to step 7:
912 goes into 7172 7 times with a remainder of 788.
The number 7 becomes the next digit in our result. 
Result so far: 1577.0
The remainder is 788 after subtracting 6384 from 7172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Step 8:
912 goes into 7880 8 times with a remainder of 584.
The next digit of our result is 8. 
Result so far: 1577.8
If we subtract 7296 from 7880, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 9:
5840 divided by 912 is 6 with a remainder of 368.
Put 6 as the next digit of the answer. 
Result so far: 1577.86
If we take 5472 away from 5840, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 10:
If we divide 3680 by 912, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 1577.864
Subtracting 3648 from 3680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
320 divided by 912 is 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 1577.864
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
When dividing 3200 by 912, we get 3 with a remainder of 464.
The next digit of our result is 3. 
Result so far: 1577.86403
If we subtract 2736 from 3200, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 13:
4640 divided by 912 is 5 with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 1577.864035
Subtract 4560 from 4640 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
If we divide 800 by 912, we get 0 and a remainder of 800.
The next digit of our result is 0. 
Result so far: 1577.864035
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 15:
The number 912 fits into 8000 8 times, leaving a remainder of 704.
The next digit of our result is 8. 
Result so far: 1577.86403508
If we take 7296 away from 8000, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The final result is 1577.86403508 with a remainder of 7.04e-07.
