We look at the division of 931865 by 3 
The aim is to understand the frequency of 3 in 931865.

On to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 9 from 9 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Moving on to step 2:
3 goes into 3 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Advancing to step 3:
1 divided by 3 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 310.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Let's proceed to step 4:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 3106.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Let's proceed to step 5:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 31062.0
Subtract 6 from 6 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Moving on to step 6:
If we divide 5 by 3, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 310621.0
The remainder is 2 after subtracting 3 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 310621.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 310621.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 310621.66 with a balance of 0.002.
