Let's divide 503599 by 6
The aim is to understand the frequency of 6 in 503599.

Going ahead to step 1:
6 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 6

Step 2:
6 can be fit into 50 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 48 from 50 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 6

Moving on to step 3:
If we divide 23 by 6, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 18 from 23 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 6

On to step 4:
55 divided by 6 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 839.0
If we take 54 away from 55, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 6

Going ahead to step 5:
6 goes into 19 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 8393.0
Subtract 18 from 19 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 6

On to step 6:
The number 6 fits into 19 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 83933.0
The remainder is 1 after subtracting 18 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
6 can be fit into 10 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 83933.1
Subtracting 6 from 10 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 6 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 83933.16
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 83933.166
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 83933.166 with a remainder of 0.0004.
