We're dividing 821091 by 48 
We're looking to find how many times 48 goes into 821091.

Advancing to step 1:
When dividing 8 by 48, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 48

Moving on to step 2:
82 divided by 48 is 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 48 from 82, we get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 48

Moving on to step 3:
341 divided by 48 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 336 from 341, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 48

Step 4:
50 divided by 48 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 171.0
If we subtract 48 from 50, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 48

Going ahead to step 5:
29 divided by 48 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 1710.0
The remainder is 29 after subtracting 0 from 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 48

Going ahead to step 6:
When dividing 291 by 48, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 17106.0
If we subtract 288 from 291, we get 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:
48 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 17106.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 48, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 17106.06
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.

Let's proceed to step 9:
48 can be fit into 120 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 17106.062
If we take 96 away from 120, we end up 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.

On to step 10:
The number 48 fits into 240 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 17106.0625
Deduct 240 from 240 and we're left 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.

Let's proceed to step 11:
If we divide 0 by 48, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17106.0625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
48 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17106.0625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 17106.0625, with a leftover of 0.0.
