We look at the division of 629475 by 3 
The aim is to understand the frequency of 3 in 629475.

Let's proceed to step 1:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Advancing to step 2:
If we divide 2 by 3, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Step 3:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Subtracting 27 from 29 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

On to step 4:
The number 3 fits into 24 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2098.0
If we subtract 24 from 24, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Let's proceed to step 5:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 20982.0
Deduct 6 from 7 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Advancing to step 6:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 209825.0
The remainder is 0 after subtracting 15 from 15.
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 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 209825.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 209825.0
Subtracting 0 from 0 leaves us 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.

Our division results in 209825.0 with a remaining 0.0.
