We're dividing 490421 by 48 
We want to figure out the number of times 490421 can be divided by 48.

Moving on to step 1:
The number 48 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 48

Moving on to step 2:
When dividing 49 by 48, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 48 away from 49, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 48

Going ahead to step 3:
48 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 48

Moving on to step 4:
The number 48 fits into 104 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 96 from 104, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 48

Let's proceed to step 5:
48 can be fit into 82 1 times, resulting in a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1021.0
Deduct 48 from 82 and we're left with 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 48

Going ahead to step 6:
The number 48 fits into 341 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 10217.0
The remainder is 5 after subtracting 336 from 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
50 divided by 48 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 10217.1
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 48 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10217.1
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 48, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 10217.104
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 48, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 10217.1041
Subtracting 48 from 80 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
If we divide 320 by 48, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 10217.10416
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
When dividing 320 by 48, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 10217.104166
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 10217.104166, and the remainder is 3.2e-06.
