We look at the division of 386666 by 75 
Let's see how many times 75 fits into 386666.

Step 1:
75 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 75

On to step 2:
The number 75 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 75

Advancing to step 3:
When dividing 386 by 75, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 375 from 386, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 75

Advancing to step 4:
75 can be fit into 116 1 times, resulting in a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
The remainder is 41 after subtracting 75 from 116.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 75

On to step 5:
If we divide 416 by 75, we get 5 and a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 515.0
Subtract 375 from 416 to get 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 75

Let's proceed to step 6:
If we divide 416 by 75, we get 5 and a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 5155.0
Subtract 375 from 416 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
When dividing 410 by 75, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5155.5
If we subtract 375 from 410, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
75 can be fit into 350 4 times, resulting in a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 5155.54
If we take 300 away from 350, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 5155.546
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 5155.5466
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 5155.5466 with a remaining 0.0005.
