We're dividing 248932 by 3 
The aim is to understand the frequency of 3 in 248932.

On to step 1:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Advancing to step 2:
3 can be fit into 24 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

On to step 3:
The number 3 fits into 8 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 82.0
The remainder is 2 after subtracting 6 from 8.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Step 4:
3 can be fit into 29 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 829.0
If we subtract 27 from 29, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Advancing to step 5:
When dividing 23 by 3, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 8297.0
If we take 21 away from 23, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Going ahead to step 6:
22 divided by 3 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 82977.0
Deduct 21 from 22 and we're left 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.

Advancing to step 7:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 82977.3
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.

Advancing to step 8:
3 goes into 10 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 82977.33
If we take 9 away from 10, 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.

After the division, we end up with 82977.33 and a remainder of 0.001.
