821358 ÷ 48 
Our goal is to divide 821358 by 48.

Going ahead to step 1:
When dividing 8 by 48, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 48

Step 2:
48 can be fit into 82 1 times, resulting in a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 48 from 82 leaves us with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 48

Moving on to step 3:
341 divided by 48 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 336 from 341 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 48

Let's proceed to step 4:
When dividing 53 by 48, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
The remainder is 5 after subtracting 48 from 53.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 48

Step 5:
When dividing 55 by 48, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1711.0
The remainder is 7 after subtracting 48 from 55.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 48

Advancing to step 6:
48 goes into 78 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 17111.0
The remainder is 30 after subtracting 48 from 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
300 divided by 48 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 17111.6
If we subtract 288 from 300, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
When dividing 120 by 48, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 17111.62
Deduct 96 from 120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
48 goes into 240 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 17111.625
If we subtract 240 from 240, 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.

Advancing to step 10:
48 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17111.625
Subtract 0 from 0 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.

Advancing to step 11:
When dividing 0 by 48, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17111.625
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.

After the division, we end up with 17111.625 and a remainder of 0.0.
