We divide 646978 by 87
We're looking to find how many times 87 goes into 646978.

Going ahead 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
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 87

Let's proceed to step 2:
87 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 87

Let's proceed to step 3:
When dividing 646 by 87, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 609 from 646, we get 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 87

On to step 4:
87 goes into 379 4 times with a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 348 from 379 and we're left with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 87

Step 5:
The number 87 fits into 317 3 times, leaving a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 743.0
If we subtract 261 from 317, we get 56.
Append the next digit (8) from the dividend to 56 and continue with: 568 / 87

Going ahead to step 6:
87 can be fit into 568 6 times, resulting in a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 7436.0
Subtract 522 from 568 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
87 goes into 460 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 7436.5
Subtracting 435 from 460 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
When dividing 250 by 87, we get 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 7436.52
If we take 174 away from 250, we end up 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 9:
760 divided by 87 is 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 7436.528
Subtracting 696 from 760 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
87 can be fit into 640 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 7436.5287
Deduct 609 from 640 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
If we divide 310 by 87, we get 3 and a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 7436.52873
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
87 goes into 490 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 7436.528735
Subtract 435 from 490 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
When dividing 550 by 87, we get 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 7436.5287356
If we take 522 away from 550, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
If we divide 280 by 87, we get 3 and a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 7436.52873563
Deduct 261 from 280 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 7436.52873563 with a balance of 1.9e-08.
