481357 ÷ 3 
The aim is to understand the frequency of 3 in 481357.

Going ahead to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Moving on to step 2:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 18 away from 18, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Step 3:
1 divided by 3 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 160.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

Advancing to step 4:
When dividing 13 by 3, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 1604.0
Subtract 12 from 13 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Moving on to step 5:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16045.0
Deduct 15 from 15 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

Step 6:
When dividing 7 by 3, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 160452.0
Deduct 6 from 7 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

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: 160452.3
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 160452.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 160452.33, and the remainder is 0.001.
