We look at the division of 387592 by 86 
Our goal is to divide 387592 by 86.

Step 1:
86 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 86

On to step 2:
86 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 86

Step 3:
The number 86 fits into 387 4 times, leaving a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 43 after subtracting 344 from 387.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 86

Going ahead to step 4:
The number 86 fits into 435 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 430 from 435 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 86

Moving on to step 5:
The number 86 fits into 59 0 times, leaving a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 450.0
The remainder is 59 after subtracting 0 from 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 86

Let's proceed to step 6:
86 goes into 592 6 times with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 4506.0
Deduct 516 from 592 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 7:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 4506.8
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
86 goes into 720 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 4506.88
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 4506.88 with a remainder of 0.032.
