35881 divided by 3 
The aim is to understand the frequency of 3 in 35881.

Let's proceed to step 1:
3 divided by 3 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

On 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: 11.0
Subtract 3 from 5 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Moving on to step 3:
The number 3 fits into 28 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtract 27 from 28 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Advancing to step 4:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 1196.0
Subtract 18 from 18 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Advancing to step 5:
3 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 11960.0
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.

Let's proceed to step 6:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 11960.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 11960.33
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.

After the division, we end up with 11960.33 and a remainder of 0.001.
