230945 ÷ 3 
The aim is to understand the frequency of 3 in 230945.

Advancing to 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
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

On to step 2:
23 divided by 3 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 21 from 23 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Advancing to step 3:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 18 from 20 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Step 4:
If we divide 29 by 3, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 769.0
Subtracting 27 from 29 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Advancing to step 5:
3 goes into 24 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 7698.0
The remainder is 0 after subtracting 24 from 24.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Advancing 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: 76981.0
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.

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: 76981.6
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.

Moving on to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 76981.66
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.

The quotient of the division is 76981.66, and the remainder is 0.002.
