490441 ÷ 48 
Our goal is to divide 490441 by 48.

Advancing to step 1:
When dividing 4 by 48, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 48

Step 2:
If we divide 49 by 48, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 48 from 49 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 48

On to step 3:
If we divide 10 by 48, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 48

Step 4:
48 can be fit into 104 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtracting 96 from 104 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 48

Going ahead to step 5:
When dividing 84 by 48, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1021.0
Deduct 48 from 84 and we're left with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 48

Moving on to step 6:
48 can be fit into 361 7 times, resulting in a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 10217.0
If we subtract 336 from 361, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
48 can be fit into 250 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 10217.5
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 48 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 10217.52
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
48 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10217.52
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
48 goes into 400 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 10217.5208
Subtracting 384 from 400 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 10217.52083
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
If we divide 160 by 48, we get 3 and a remainder of 16.
The next digit of our result is 3. 
Result so far: 10217.520833
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 10217.520833, with a leftover of 1.6e-06.
