We're dividing 441853 by 3 
We're looking to find how many times 3 goes into 441853.

Advancing 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 (4) from the dividend and append it to 1, then repeat: 14 / 3

Step 2:
When dividing 14 by 3, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 12 away from 14, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Advancing to step 3:
If we divide 21 by 3, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 147.0
If we take 21 away from 21, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Going ahead to step 4:
8 divided by 3 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 1472.0
If we subtract 6 from 8, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Step 5:
The number 3 fits into 25 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 14728.0
The remainder is 1 after subtracting 24 from 25.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Advancing to step 6:
The number 3 fits into 13 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 147284.0
If we take 12 away from 13, 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.

Step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 147284.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 147284.33
If we subtract 9 from 10, we get 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 147284.33 with a remainder of 0.001.
