Let's divide 67128172 by 3
The aim is to understand the frequency of 3 in 67128172.

Moving on to step 1:
6 divided by 3 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 6 from 6, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 3

Moving on to step 2:
When dividing 7 by 3, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 6 away from 7, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

Moving on to step 3:
If we divide 11 by 3, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
Subtract 9 from 11 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Let's proceed to step 4:
3 goes into 22 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 2237.0
Subtract 21 from 22 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

On to step 5:
3 goes into 18 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 22376.0
If we subtract 18 from 18, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Step 6:
If we divide 1 by 3, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 223760.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Let's proceed to step 7:
3 goes into 17 5 times with a remainder of 2.
The next digit of our result is 5. 
Result so far: 2237605.0
Subtracting 15 from 17 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Going ahead to step 8:
22 divided by 3 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 22376057.0
If we take 21 away from 22, we end up 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.

Moving on to step 9:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 22376057.3
Subtract 9 from 10 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.

Step 10:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 22376057.33
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.

The quotient of the division is 22376057.33, and the remainder is 0.001.
