We're dividing 387907 by 87 
Let's see how many times 87 fits into 387907.

Advancing to step 1:
87 goes into 3 0 times with 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.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 87

Advancing to step 2:
87 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 87

Going ahead to step 3:
If we divide 387 by 87, we get 4 and a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 39 after subtracting 348 from 387.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 87

Step 4:
The number 87 fits into 399 4 times, leaving a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 44.0
The remainder is 51 after subtracting 348 from 399.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 87

On to step 5:
87 goes into 510 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 445.0
Subtract 435 from 510 to get 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 87

Advancing to step 6:
The number 87 fits into 757 8 times, leaving a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 4458.0
Subtracting 696 from 757 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
When dividing 610 by 87, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 4458.7
Subtracting 609 from 610 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
When dividing 10 by 87, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4458.7
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 87 fits into 100 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 4458.701
Subtracting 87 from 100 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
The number 87 fits into 130 1 times, leaving a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 4458.7011
If we subtract 87 from 130, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Our division results in 4458.7011 with a remaining 0.00043.
