We look at the division of 448533 by 3 
We want to figure out the number of times 448533 can be divided by 3.

Advancing to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Let's proceed to step 2:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 12 from 14 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Advancing to step 3:
28 divided by 3 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 149.0
If we subtract 27 from 28, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Step 4:
If we divide 15 by 3, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1495.0
If we subtract 15 from 15, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Advancing to step 5:
If we divide 3 by 3, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 14951.0
If we take 3 away from 3, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

Advancing to step 6:
If we divide 3 by 3, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 149511.0
Subtracting 3 from 3 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 149511.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 149511.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 149511.0 with a remainder of 0.0.
