We look at the division of 98130719 by 3 
The aim is to understand the frequency of 3 in 98130719.

Advancing to step 1:
If we divide 9 by 3, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Step 2:
8 divided by 3 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 6 from 8 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Step 3:
3 goes into 21 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 327.0
Deduct 21 from 21 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

Going ahead to step 4:
The number 3 fits into 3 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 3271.0
If we take 3 away from 3, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Step 5:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32710.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

Moving on to step 6:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 327102.0
If we take 6 away from 7, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

On to step 7:
11 divided by 3 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3271023.0
If we subtract 9 from 11, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Moving on to step 8:
If we divide 29 by 3, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 32710239.0
If we take 27 away from 29, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 32710239.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 32710239.66
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 32710239.66 and a remainder of 0.002.
