Let's divide 72204154 by 3
The aim is to understand the frequency of 3 in 72204154.

Advancing to step 1:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 3

On to step 2:
The number 3 fits into 12 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 24.0
If we take 12 away from 12, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

Step 3:
2 divided by 3 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 240.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 3

Let's proceed to step 4:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2406.0
The remainder is 2 after subtracting 18 from 20.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Going ahead to step 5:
If we divide 24 by 3, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 24068.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

On to step 6:
3 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 240680.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Let's proceed to step 7:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2406805.0
Deduct 15 from 15 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Let's proceed to step 8:
3 goes into 4 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 24068051.0
Subtract 3 from 4 to 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.

On to step 9:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 24068051.3
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.

Advancing to step 10:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 24068051.33
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.

The final result is 24068051.33 with a remainder of 0.001.
