We divide 918612 by 3
The aim is to understand the frequency of 3 in 918612.

Going ahead to step 1:
When dividing 9 by 3, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

On to step 2:
If we divide 1 by 3, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Going ahead to step 3:
If we divide 18 by 3, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 306.0
Subtracting 18 from 18 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 3

Moving on to step 4:
When dividing 6 by 3, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 3062.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Moving on to step 5:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 30620.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Going ahead to step 6:
If we divide 12 by 3, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 306204.0
Subtract 12 from 12 to 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.
The next digit of our result is 0. 
Result so far: 306204.0
If we subtract 0 from 0, 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.

Moving on to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 306204.0
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 306204.0 with a remaining 0.0.
