We divide 19884 by 3
The aim is to understand the frequency of 3 in 19884.

Advancing to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Going ahead to step 2:
3 goes into 19 6 times with a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 18 from 19, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

On to step 3:
If we divide 18 by 3, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we subtract 18 from 18, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Moving on to step 4:
8 divided by 3 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 662.0
If we subtract 6 from 8, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Moving on to step 5:
When dividing 24 by 3, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 6628.0
The remainder is 0 after subtracting 24 from 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 6:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6628.0
If we take 0 away from 0, we end up 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.

Going ahead to step 7:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6628.0
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.

The final outcome is 6628.0, with a leftover of 0.0.
