Let's divide 448590 by 4
Let's see how many times 4 fits into 448590.

On to step 1:
When dividing 4 by 4, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 4 from 4 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 4

Step 2:
When dividing 4 by 4, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 4 from 4 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 4

Advancing to step 3:
If we divide 8 by 4, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we take 8 away from 8, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 4

Advancing to step 4:
4 can be fit into 5 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1121.0
If we take 4 away from 5, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Moving on to step 5:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 11214.0
If we take 16 away from 19, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 4

Let's proceed to step 6:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 112147.0
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 112147.5
Subtract 20 from 20 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.

Moving on to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 112147.5
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.

Let's proceed to step 9:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 112147.5
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 112147.5 with a balance of 0.0.
