We divide 339760 by 6
The aim is to understand the frequency of 6 in 339760.

Moving on to step 1:
3 divided by 6 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 6

Step 2:
6 can be fit into 33 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 30 from 33 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Going ahead to step 3:
When dividing 39 by 6, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we take 36 away from 39, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 6

Moving on to step 4:
If we divide 37 by 6, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 566.0
If we subtract 36 from 37, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 6

Step 5:
16 divided by 6 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 5662.0
Subtract 12 from 16 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 6

Step 6:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 56626.0
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.

Advancing to step 7:
6 goes into 40 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 56626.6
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 56626.66
Subtract 36 from 40 to get 4.
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 outcome is 56626.66, with a leftover of 0.004.
