We look at the division of 732352 by 3 
The aim is to understand the frequency of 3 in 732352.

Let's proceed to step 1:
If we divide 7 by 3, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 6 from 7 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Advancing to step 2:
13 divided by 3 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 12 from 13 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Going ahead to step 3:
When dividing 12 by 3, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
Subtract 12 from 12 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

On to step 4:
If we divide 3 by 3, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 2441.0
Subtract 3 from 3 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Moving on to step 5:
3 can be fit into 5 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 24411.0
Subtract 3 from 5 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Advancing to step 6:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 244117.0
Subtract 21 from 22 to 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.

On to step 7:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 244117.3
Subtract 9 from 10 to 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.

On to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 244117.33
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 244117.33 and a remainder of 0.001.
