We divide 390453 by 6
The aim is to understand the frequency of 6 in 390453.

Moving on to step 1:
The number 6 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 6

Advancing to step 2:
When dividing 39 by 6, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 36 from 39 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 6

Step 3:
30 divided by 6 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 65.0
The remainder is 0 after subtracting 30 from 30.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 6

Moving on to step 4:
The number 6 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 650.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 6

Moving on to step 5:
If we divide 45 by 6, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 6507.0
If we take 42 away from 45, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 6

On to step 6:
6 goes into 33 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 65075.0
If we take 30 away from 33, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 6 fits into 30 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 65075.5
If we take 30 away from 30, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
6 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 65075.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 6, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 65075.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 65075.5, with a leftover of 0.0.
