We're dividing 448198 by 3 
Let's see how many times 3 fits into 448198.

Step 1:
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: 1.0
Subtract 3 from 4 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Advancing 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.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Moving on to step 3:
28 divided by 3 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 149.0
The remainder is 1 after subtracting 27 from 28.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Step 4:
3 goes into 11 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1493.0
Subtracting 9 from 11 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Let's proceed to step 5:
When dividing 29 by 3, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 14939.0
The remainder is 2 after subtracting 27 from 29.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Going ahead to step 6:
3 goes into 28 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 149399.0
If we subtract 27 from 28, 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.

Going ahead to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 149399.3
The remainder is 1 after subtracting 9 from 10.
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:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 149399.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 149399.33 with a balance of 0.001.
