404618 ÷ 3 
The aim is to understand the frequency of 3 in 404618.

Advancing to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Let's proceed to step 2:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 9 from 10 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Going ahead to step 3:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 134.0
If we take 12 away from 14, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Advancing to step 4:
The number 3 fits into 26 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 1348.0
Subtract 24 from 26 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

On to step 5:
If we divide 21 by 3, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 13487.0
Subtracting 21 from 21 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Let's proceed to step 6:
8 divided by 3 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 134872.0
Subtract 6 from 8 to 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.

On to step 7:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 134872.6
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.

Advancing to step 8:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 134872.66
The remainder is 2 after subtracting 18 from 20.
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 134872.66, and the remainder is 0.002.
