We're dividing 446549 by 3 
We want to figure out the number of times 446549 can be divided by 3.

Let's proceed to step 1:
3 goes into 4 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Advancing to step 2:
If we divide 14 by 3, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 12 from 14, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Going ahead to step 3:
3 goes into 26 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 148.0
Subtracting 24 from 26 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Step 4:
25 divided by 3 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1488.0
If we take 24 away from 25, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

On to step 5:
If we divide 14 by 3, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 14884.0
Deduct 12 from 14 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Going ahead to step 6:
3 goes into 29 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 148849.0
Subtracting 27 from 29 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 148849.6
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 148849.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 148849.66 with a remaining 0.002.
