We're dividing 65907660 by 3 
The aim is to understand the frequency of 3 in 65907660.

Advancing to step 1:
3 can be fit into 6 2 times, resulting in 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.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Going ahead to step 2:
If we divide 5 by 3, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 3 from 5 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Let's proceed to step 3:
The number 3 fits into 29 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 219.0
If we take 27 away from 29, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 3

Moving on to step 4:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 2196.0
If we take 18 away from 20, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Let's proceed to step 5:
3 can be fit into 27 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 21969.0
If we subtract 27 from 27, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Going ahead to step 6:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 219692.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Advancing to step 7:
When dividing 6 by 3, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2196922.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Moving on to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 21969220.0
Subtracting 0 from 0 leaves us 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.

Step 9:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21969220.0
Deduct 0 from 0 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.

Step 10:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21969220.0
If we take 0 away from 0, we end up 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.

After the division, we end up with 21969220.0 and a remainder of 0.0.
