We look at the division of 993021 by 48 
Let's see how many times 48 fits into 993021.

Moving on to step 1:
9 divided by 48 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 48

Going ahead to step 2:
48 goes into 99 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 96 from 99 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 48

Step 3:
If we divide 33 by 48, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 48

Let's proceed to step 4:
330 divided by 48 is 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
If we take 288 away from 330, we end up with 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 48

Step 5:
When dividing 422 by 48, we get 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 2068.0
If we subtract 384 from 422, we get 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 48

Step 6:
If we divide 381 by 48, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 20687.0
If we subtract 336 from 381, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
450 divided by 48 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 20687.9
Subtracting 432 from 450 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
48 can be fit into 180 3 times, resulting in a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 20687.93
If we subtract 144 from 180, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
The number 48 fits into 360 7 times, leaving a remainder of 24.
The next digit of our result is 7. 
Result so far: 20687.937
Deduct 336 from 360 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.

Step 10:
The number 48 fits into 240 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20687.9375
If we take 240 away from 240, 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.

Step 11:
When dividing 0 by 48, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20687.9375
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.

Step 12:
If we divide 0 by 48, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 20687.9375
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.

The final result is 20687.9375 with a remainder of 0.0.
