947729 ÷ 3 
The aim is to understand the frequency of 3 in 947729.

Advancing to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 9 away from 9, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Moving on to step 2:
If we divide 4 by 3, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 3 from 4, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Advancing to step 3:
17 divided by 3 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 315.0
The remainder is 2 after subtracting 15 from 17.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Step 4:
3 goes into 27 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3159.0
Deduct 27 from 27 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Let's proceed to step 5:
3 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 31590.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 3

Going ahead to step 6:
3 goes into 29 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 315909.0
The remainder is 2 after subtracting 27 from 29.
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 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 315909.6
Subtract 18 from 20 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.

Moving on to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 315909.66
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 final outcome is 315909.66, with a leftover of 0.002.
