Let's divide 708075 by 3
The aim is to understand the frequency of 3 in 708075.

Going ahead to step 1:
When dividing 7 by 3, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

On to step 2:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 9 from 10 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Going ahead to step 3:
If we divide 18 by 3, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 236.0
Subtracting 18 from 18 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Moving on to step 4:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2360.0
If we subtract 0 from 0, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

On to step 5:
7 divided by 3 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 23602.0
Subtracting 6 from 7 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Moving on to step 6:
When dividing 15 by 3, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 236025.0
If we subtract 15 from 15, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 236025.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 236025.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 236025.0 with a remaining 0.0.
