Let's divide 647859 by 87
We're looking to find how many times 87 goes into 647859.

Moving on to step 1:
If we divide 6 by 87, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 87

Going ahead to step 2:
The number 87 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 87

Moving on to step 3:
647 divided by 87 is 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 609 from 647 and we're left with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 87

Step 4:
If we divide 388 by 87, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 348 from 388 to get 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 87

Step 5:
The number 87 fits into 405 4 times, leaving a remainder of 57.
The next digit of our result is 4. 
Result so far: 744.0
The remainder is 57 after subtracting 348 from 405.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 87

On to step 6:
579 divided by 87 is 6 with a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 7446.0
Subtracting 522 from 579 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
If we divide 570 by 87, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 7446.6
If we take 522 away from 570, we end up 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.

Step 8:
When dividing 480 by 87, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 7446.65
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
When dividing 450 by 87, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 7446.655
Deduct 435 from 450 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 7446.655, with a leftover of 0.0015.
