We look at the division of 976081 by 3 
The aim is to understand the frequency of 3 in 976081.

Moving on to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 9 from 9 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Moving on to step 2:
If we divide 7 by 3, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtracting 6 from 7 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 3

Going ahead to step 3:
16 divided by 3 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 325.0
The remainder is 1 after subtracting 15 from 16.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Going ahead to step 4:
When dividing 10 by 3, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3253.0
Subtract 9 from 10 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

Let's proceed to step 5:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 32536.0
If we subtract 18 from 18, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Let's proceed to step 6:
3 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 325360.0
If we take 0 away from 1, we end up 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.

Step 7:
3 goes into 10 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 325360.3
Subtracting 9 from 10 leaves us 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.

Step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 325360.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 325360.33 with a remaining 0.001.
