479087 ÷ 3 
The aim is to understand the frequency of 3 in 479087.

Going ahead to step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

On to step 2:
When dividing 17 by 3, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 15 from 17 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

On to step 3:
3 can be fit into 29 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 159.0
Subtracting 27 from 29 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

On to step 4:
When dividing 20 by 3, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1596.0
If we subtract 18 from 20, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

Moving on to step 5:
The number 3 fits into 28 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 15969.0
Deduct 27 from 28 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Let's proceed to step 6:
3 goes into 17 5 times with a remainder of 2.
The next digit of our result is 5. 
Result so far: 159695.0
Subtracting 15 from 17 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.

Let's proceed to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 159695.6
The remainder is 2 after subtracting 18 from 20.
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 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 159695.66
The remainder is 2 after subtracting 18 from 20.
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 159695.66, with a leftover of 0.002.
