Let's divide 704123 by 3
The aim is to understand the frequency of 3 in 704123.

Let's proceed to step 1:
The number 3 fits into 7 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

Going ahead to step 2:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 9 from 10 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Moving on to step 3:
14 divided by 3 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 234.0
The remainder is 2 after subtracting 12 from 14.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Step 4:
The number 3 fits into 21 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 2347.0
If we subtract 21 from 21, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

On to step 5:
If we divide 2 by 3, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 23470.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Moving on to step 6:
3 goes into 23 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 234707.0
If we take 21 away from 23, we end up 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.

On to step 7:
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: 234707.6
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.

Let's proceed to step 8:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 234707.66
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.

The final outcome is 234707.66, with a leftover of 0.002.
