We're dividing 56248 by 3 
The aim is to understand the frequency of 3 in 56248.

On to step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 3 away from 5, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Moving on to step 2:
26 divided by 3 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 24 from 26 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

Going ahead to step 3:
If we divide 22 by 3, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Subtract 21 from 22 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Let's proceed to step 4:
If we divide 14 by 3, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1874.0
Deduct 12 from 14 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

On to step 5:
If we divide 28 by 3, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 18749.0
If we take 27 away from 28, 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 6:
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: 18749.3
Deduct 9 from 10 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.

Going ahead to step 7:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 18749.33
Deduct 9 from 10 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.

After the division, we end up with 18749.33 and a remainder of 0.001.
