404074 divided by 3 
We're looking to find how many times 3 goes into 404074.

On to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

On to step 2:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 9 from 10 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Going ahead to step 3:
The number 3 fits into 14 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 134.0
If we take 12 away from 14, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Going ahead to step 4:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 1346.0
Subtracting 18 from 20 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Moving on to step 5:
If we divide 27 by 3, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 13469.0
Subtract 27 from 27 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

On to step 6:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 134691.0
If we take 3 away from 4, we end up 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.

Let's proceed to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 134691.3
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.

Let's proceed to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 134691.33
If we take 9 away from 10, we end up 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 final result is 134691.33 with a remainder of 0.001.
