We look at the division of 388516 by 75 
We're looking to find how many times 75 goes into 388516.

Let's proceed to step 1:
3 divided by 75 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 75

Step 2:
If we divide 38 by 75, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 75

Let's proceed to step 3:
388 divided by 75 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 375 from 388 leaves us with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 75

Step 4:
75 goes into 135 1 times with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 75 from 135 and we're left with 60.
Fetch the next digit (1) from the dividend, attach it to 60 and continue: 601 / 75

Step 5:
75 can be fit into 601 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 518.0
If we subtract 600 from 601, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 75

Let's proceed to step 6:
The number 75 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 5180.0
Deduct 0 from 16 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
160 divided by 75 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 5180.2
The remainder is 10 after subtracting 150 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 75 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 5180.21
The remainder is 25 after subtracting 75 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
75 goes into 250 3 times with a remainder of 25.
The next digit of our result is 3. 
Result so far: 5180.213
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
250 divided by 75 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 5180.2133
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 5180.2133 with a remainder of 0.00025.
