We're dividing 539030 by 6 
The aim is to understand the frequency of 6 in 539030.

On to step 1:
When dividing 5 by 6, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 6

Step 2:
53 divided by 6 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 48 away from 53, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 6

On to step 3:
The number 6 fits into 59 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we take 54 away from 59, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 6

On to step 4:
The number 6 fits into 50 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 898.0
Deduct 48 from 50 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 6

Going ahead to step 5:
When dividing 23 by 6, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 8983.0
The remainder is 5 after subtracting 18 from 23.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 6

Moving on to step 6:
When dividing 50 by 6, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 89838.0
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 89838.3
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 89838.33
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 quotient of the division is 89838.33, and the remainder is 0.002.
