780539 divided by 6 
The aim is to understand the frequency of 6 in 780539.

Advancing to step 1:
6 can be fit into 7 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 6 from 7, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 6

Moving on to step 2:
If we divide 18 by 6, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 18 away from 18, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 6

Advancing to step 3:
6 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 6

Let's proceed to step 4:
6 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 1300.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 6

Going ahead to step 5:
When dividing 53 by 6, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 13008.0
Subtracting 48 from 53 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 6

Moving on to step 6:
If we divide 59 by 6, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 130089.0
The remainder is 5 after subtracting 54 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 6 fits into 50 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 130089.8
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 6 fits into 20 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 130089.83
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
6 goes into 20 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 130089.833
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 130089.833, with a leftover of 0.0002.
