We look at the division of 393858 by 4 
We want to figure out the number of times 393858 can be divided by 4.

Moving on to step 1:
The number 4 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 take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 4

Going ahead to step 2:
If we divide 39 by 4, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 36 from 39 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 4

Let's proceed to step 3:
The number 4 fits into 33 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we take 32 away from 33, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 4

Let's proceed to step 4:
18 divided by 4 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 984.0
If we take 16 away from 18, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 4

Advancing to step 5:
4 can be fit into 25 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 9846.0
The remainder is 1 after subtracting 24 from 25.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

Advancing to step 6:
When dividing 18 by 4, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 98464.0
Subtracting 16 from 18 leaves us 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.

Moving on to step 7:
4 goes into 20 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 98464.5
If we subtract 20 from 20, 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 8:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 98464.5
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.

Going ahead to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 98464.5
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 98464.5 with a remainder of 0.0.
