687642 divided by 87 
We want to figure out the number of times 687642 can be divided by 87.

Step 1:
6 divided by 87 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 87

Let's proceed to step 2:
87 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 87

Let's proceed to step 3:
87 goes into 687 7 times with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 609 from 687, we get 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 87

Advancing to step 4:
The number 87 fits into 786 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 79.0
If we subtract 783 from 786, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 87

Let's proceed to step 5:
87 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 790.0
Deduct 0 from 34 and we're left with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 87

Moving on to step 6:
The number 87 fits into 342 3 times, leaving a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 7903.0
If we subtract 261 from 342, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
When dividing 810 by 87, we get 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 7903.9
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 7903.93
The remainder is 9 after subtracting 261 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
If we divide 90 by 87, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7903.931
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
87 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 7903.931
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
87 goes into 300 3 times with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 7903.93103
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
If we divide 390 by 87, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 7903.931034
If we take 348 away from 390, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
If we divide 420 by 87, we get 4 and a remainder of 72.
The next digit of our result is 4. 
Result so far: 7903.9310344
The remainder is 72 after subtracting 348 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 7903.9310344 with a balance of 7.2e-07.
