We look at the division of 385947 by 86 
Our goal is to divide 385947 by 86.

Advancing to step 1:
If we divide 3 by 86, we get 0 and 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 (8) from the dividend, attach it to 3 and continue: 38 / 86

Going ahead to step 2:
When dividing 38 by 86, we get 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 86

Step 3:
The number 86 fits into 385 4 times, leaving a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 344 away from 385, we end up with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 86

Going ahead to step 4:
The number 86 fits into 419 4 times, leaving a remainder of 75.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we take 344 away from 419, we end up with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 86

Advancing to step 5:
86 goes into 754 8 times with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 448.0
Subtracting 688 from 754 leaves us with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 86

Moving on to step 6:
86 can be fit into 667 7 times, resulting in a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 4487.0
If we subtract 602 from 667, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
650 divided by 86 is 7 with a remainder of 48.
The next digit of our result is 7. 
Result so far: 4487.7
Subtracting 602 from 650 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
480 divided by 86 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4487.75
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 86 fits into 500 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 4487.755
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 4487.755 with a remaining 0.007.
