We're dividing 631432 by 3 
The aim is to understand the frequency of 3 in 631432.

On to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

Moving on to step 2:
3 divided by 3 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 3 away from 3, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Going ahead to step 3:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Moving on to step 4:
When dividing 14 by 3, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 2104.0
If we take 12 away from 14, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

On to step 5:
When dividing 23 by 3, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 21047.0
If we take 21 away from 23, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Let's proceed to step 6:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 210477.0
The remainder is 1 after subtracting 21 from 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 210477.3
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 210477.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 210477.33 with a balance of 0.001.
