Let's divide 263759 by 3
The aim is to understand the frequency of 3 in 263759.

Step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

On to step 2:
3 goes into 26 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 2 after subtracting 24 from 26.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Advancing to step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 21 from 23 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Let's proceed to step 4:
3 can be fit into 27 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 879.0
If we subtract 27 from 27, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Step 5:
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: 8791.0
The remainder is 2 after subtracting 3 from 5.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Moving on to step 6:
3 can be fit into 29 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 87919.0
The remainder is 2 after subtracting 27 from 29.
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 7:
3 goes into 20 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 87919.6
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.

Step 8:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 87919.66
Subtracting 18 from 20 leaves us 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.

Our division results in 87919.66 with a remaining 0.002.
