We divide 390016 by 87
Let's see how many times 87 fits into 390016.

On to step 1:
The number 87 fits into 3 0 times, leaving 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.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 87

Let's proceed to step 2:
39 divided by 87 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 87

Let's proceed to step 3:
87 can be fit into 390 4 times, resulting in a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 348 from 390, we get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 87

On to step 4:
When dividing 420 by 87, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtract 348 from 420 to get 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 87

Moving on to step 5:
87 goes into 721 8 times with a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 448.0
Deduct 696 from 721 and we're left with 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 87

On to step 6:
When dividing 256 by 87, we get 2 with a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 4482.0
Deduct 174 from 256 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 7:
The number 87 fits into 820 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 4482.9
Deduct 783 from 820 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
If we divide 370 by 87, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 4482.94
The remainder is 22 after subtracting 348 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
87 goes into 220 2 times with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 4482.942
Deduct 174 from 220 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
87 can be fit into 460 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4482.9425
Subtract 435 from 460 to 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.

Moving on to step 11:
87 goes into 250 2 times with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 4482.94252
Deduct 174 from 250 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.

Moving on to step 12:
760 divided by 87 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 4482.942528
If we subtract 696 from 760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
If we divide 640 by 87, we get 7 and a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 4482.9425287
The remainder is 31 after subtracting 609 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
When dividing 310 by 87, we get 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 4482.94252873
The remainder is 49 after subtracting 261 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 4482.94252873, with a leftover of 4.9e-08.
