We look at the division of 70241275 by 3 
The aim is to understand the frequency of 3 in 70241275.

Advancing to step 1:
If we divide 7 by 3, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Going ahead to step 2:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 9 away from 10, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Going ahead to step 3:
3 can be fit into 12 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Let's proceed to step 4:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 2341.0
Subtract 3 from 4 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Moving on to step 5:
The number 3 fits into 11 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 23413.0
Subtract 9 from 11 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 3

Step 6:
When dividing 22 by 3, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 234137.0
If we take 21 away from 22, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Going ahead to step 7:
17 divided by 3 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 2341375.0
Subtracting 15 from 17 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Going ahead to step 8:
If we divide 25 by 3, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 23413758.0
The remainder is 1 after subtracting 24 from 25.
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 9:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 23413758.3
Deduct 9 from 10 and we're left 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 10:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 23413758.33
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.

The final outcome is 23413758.33, with a leftover of 0.001.
