We divide 221992 by 3
The aim is to understand the frequency of 3 in 221992.

Step 1:
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: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Step 2:
If we divide 22 by 3, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 21 from 22 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Let's proceed to step 3:
If we divide 11 by 3, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we take 9 away from 11, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

On to step 4:
3 goes into 29 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 739.0
Deduct 27 from 29 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Moving on to step 5:
3 can be fit into 29 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 7399.0
The remainder is 2 after subtracting 27 from 29.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

On to step 6:
3 can be fit into 22 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 73997.0
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.

Let's proceed to step 7:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 73997.3
The remainder is 1 after subtracting 9 from 10.
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:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 73997.33
Subtracting 9 from 10 leaves us with 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 73997.33 with a balance of 0.001.
