768595 divided by 3 
The aim is to understand the frequency of 3 in 768595.

Step 1:
3 goes into 7 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 3

On to step 2:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 15 from 16 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Moving on to step 3:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 256.0
The remainder is 0 after subtracting 18 from 18.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Going ahead to step 4:
If we divide 5 by 3, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 2561.0
The remainder is 2 after subtracting 3 from 5.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

On to step 5:
3 goes into 29 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 25619.0
If we take 27 away from 29, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Let's proceed to step 6:
The number 3 fits into 25 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 256198.0
The remainder is 1 after subtracting 24 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 256198.3
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.

Going ahead to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 256198.33
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.

After the division, we end up with 256198.33 and a remainder of 0.001.
