Let's divide 71668932 by 3
The aim is to understand the frequency of 3 in 71668932.

Going ahead to step 1:
If we divide 7 by 3, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Let's proceed to step 2:
When dividing 11 by 3, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 9 from 11 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Advancing to step 3:
26 divided by 3 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
Subtracting 24 from 26 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Going ahead to step 4:
When dividing 26 by 3, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 2388.0
Subtracting 24 from 26 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Going ahead to step 5:
3 can be fit into 28 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 23889.0
Deduct 27 from 28 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Step 6:
The number 3 fits into 19 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 238896.0
Subtract 18 from 19 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Moving on to step 7:
If we divide 13 by 3, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 2388964.0
Deduct 12 from 13 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 3

Let's proceed to step 8:
When dividing 12 by 3, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 23889644.0
Subtracting 12 from 12 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:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23889644.0
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.

Going ahead to step 10:
If we divide 0 by 3, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23889644.0
The remainder is 0 after subtracting 0 from 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 23889644.0 and a remainder of 0.0.
