12014916 divided by 839 
The aim is to understand the frequency of 839 in 12014916.

Advancing to step 1:
When dividing 1 by 839, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 839

Going ahead to step 2:
The number 839 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 839

On to step 3:
When dividing 120 by 839, we get 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 120, we get 120.
Grab the next digit (1) from the dividend, add it to 120, then carry on: 1201 / 839

Advancing to step 4:
839 goes into 1201 1 times with a remainder of 362.
The next digit of our result is 1. 
Result so far: 1.0
If we take 839 away from 1201, we end up with 362.
Include the next digit (4) from the dividend after 362, then repeat: 3624 / 839

Going ahead to step 5:
When dividing 3624 by 839, we get 4 with a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 3356 from 3624, we get 268.
Grab the next digit (9) from the dividend, add it to 268, then carry on: 2689 / 839

Let's proceed to step 6:
839 goes into 2689 3 times with a remainder of 172.
The next digit of our result is 3. 
Result so far: 143.0
Subtracting 2517 from 2689 leaves us with 172.
Append the next digit (1) from the dividend to 172 and continue with: 1721 / 839

Moving on to step 7:
When dividing 1721 by 839, we get 2 with a remainder of 43.
The next digit of our result is 2. 
Result so far: 1432.0
If we subtract 1678 from 1721, we get 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 839

Going ahead to step 8:
839 can be fit into 436 0 times, resulting in a remainder of 436.
The number 0 becomes the next digit in our result. 
Result so far: 14320.0
Subtracting 0 from 436 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 9:
4360 divided by 839 is 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 14320.5
If we take 4195 away from 4360, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
When dividing 1650 by 839, we get 1 with a remainder of 811.
Put 1 as the next digit of the answer. 
Result so far: 14320.51
Subtracting 839 from 1650 leaves us with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Step 11:
839 goes into 8110 9 times with a remainder of 559.
Record the quotient 9 as the next digit in the result. 
Result so far: 14320.519
The remainder is 559 after subtracting 7551 from 8110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Step 12:
If we divide 5590 by 839, we get 6 and a remainder of 556.
The number 6 becomes the next digit in our result. 
Result so far: 14320.5196
Deduct 5034 from 5590 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 13:
5560 divided by 839 is 6 with a remainder of 526.
Put 6 as the next digit of the answer. 
Result so far: 14320.51966
Deduct 5034 from 5560 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

The final result is 14320.51966 with a remainder of 0.000526.
