393891 ÷ 48 
We want to figure out the number of times 393891 can be divided by 48.

Moving on to step 1:
The number 48 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 48

Going ahead to step 2:
39 divided by 48 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 48

Moving on to step 3:
48 goes into 393 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 384 away from 393, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 48

Moving on to step 4:
If we divide 98 by 48, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 96 from 98 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 48

Let's proceed to step 5:
29 divided by 48 is 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 820.0
Subtract 0 from 29 to get 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 48

Going ahead to step 6:
48 goes into 291 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 8206.0
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.
The next digit of our result is 0. 
Result so far: 8206.0
If we subtract 0 from 30, we get 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:
48 goes into 300 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 8206.06
Subtract 288 from 300 to 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:
The number 48 fits into 120 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 8206.062
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.

Step 10:
48 goes into 240 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8206.0625
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.

Moving on to step 11:
48 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8206.0625
Deduct 0 from 0 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.

Going ahead to step 12:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8206.0625
Subtracting 0 from 0 leaves us 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.

The final outcome is 8206.0625, with a leftover of 0.0.
