630992 ÷ 3 
The aim is to understand the frequency of 3 in 630992.

Going ahead to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 3

Step 2:
When dividing 3 by 3, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 3 from 3 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Going ahead to step 3:
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: 210.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Let's proceed to step 4:
9 divided by 3 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 2103.0
Subtracting 9 from 9 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Moving on to step 5:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 21033.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Moving on to step 6:
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: 210330.0
Subtract 0 from 2 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.

Let's proceed to step 7:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 210330.6
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.

Advancing to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 210330.66
If we subtract 18 from 20, we 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 210330.66, with a leftover of 0.002.
