We look at the division of 448239 by 145 
We want to divide 448239 by 145.

Going ahead to step 1:
145 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 145

Let's proceed to step 2:
145 can be fit into 44 0 times, resulting in a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 145

Moving on to step 3:
The number 145 fits into 448 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 435 from 448 and we're left with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 145

Step 4:
145 can be fit into 132 0 times, resulting in a remainder of 132.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 132, we end up with 132.
Append the next digit (3) from the dividend to 132 and continue with: 1323 / 145

Going ahead to step 5:
145 goes into 1323 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 309.0
Subtracting 1305 from 1323 leaves us with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 145

Advancing to step 6:
When dividing 189 by 145, we get 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 3091.0
Deduct 145 from 189 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
145 can be fit into 440 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 3091.3
The remainder is 5 after subtracting 435 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
50 divided by 145 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 3091.3
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
145 can be fit into 500 3 times, resulting in a remainder of 65.
The next digit of our result is 3. 
Result so far: 3091.303
If we take 435 away from 500, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 10:
The number 145 fits into 650 4 times, leaving a remainder of 70.
The next digit of our result is 4. 
Result so far: 3091.3034
The remainder is 70 after subtracting 580 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
If we divide 700 by 145, we get 4 and a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 3091.30344
Subtracting 580 from 700 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 3091.30344, and the remainder is 0.00012.
