448939 ÷ 4 
We want to divide 448939 by 4.

Moving on to step 1:
If we divide 4 by 4, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 4 away from 4, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 4

Moving on to step 2:
When dividing 4 by 4, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 4

On to step 3:
If we divide 8 by 4, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Advancing to step 4:
4 can be fit into 9 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 1122.0
If we subtract 8 from 9, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 4

Going ahead to step 5:
13 divided by 4 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 11223.0
If we take 12 away from 13, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 4

Let's proceed to step 6:
4 can be fit into 19 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 112234.0
Subtracting 16 from 19 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 112234.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 112234.75
Subtracting 20 from 20 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.

Step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 112234.75
If we subtract 0 from 0, we 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.

Step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 112234.75
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.

After the division, we end up with 112234.75 and a remainder of 0.0.
