We're dividing 72493594 by 3 
The aim is to understand the frequency of 3 in 72493594.

Going ahead to step 1:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 6 away from 7, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Advancing to step 2:
12 divided by 3 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 0 after subtracting 12 from 12.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Advancing to step 3:
When dividing 4 by 3, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 241.0
If we subtract 3 from 4, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Let's proceed to step 4:
3 goes into 19 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 2416.0
Subtract 18 from 19 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Going ahead to step 5:
If we divide 13 by 3, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 24164.0
Subtracting 12 from 13 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

On to step 6:
3 goes into 15 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 241645.0
Subtract 15 from 15 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 3

Moving on to step 7:
9 divided by 3 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 2416453.0
If we take 9 away from 9, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Let's proceed to step 8:
If we divide 4 by 3, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 24164531.0
If we take 3 away from 4, 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.

On to step 9:
10 divided by 3 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 24164531.3
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.

Let's proceed to step 10:
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: 24164531.33
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.

Our division results in 24164531.33 with a remaining 0.001.
