Let's divide 69945 by 3
The aim is to understand the frequency of 3 in 69945.

Moving on to step 1:
6 divided by 3 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Moving on to step 2:
When dividing 9 by 3, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 9 from 9 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Step 3:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Step 4:
If we divide 4 by 3, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 2331.0
Deduct 3 from 4 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Advancing to step 5:
If we divide 15 by 3, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 23315.0
Deduct 15 from 15 and we're left 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.

On to step 6:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23315.0
If we subtract 0 from 0, we get 0.
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 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: 23315.0
If we subtract 0 from 0, we get 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 result is 23315.0 with a remainder of 0.0.
