10087676 ÷ 642 
We want to figure out the number of times 10087676 can be divided by 642.

Step 1:
If we divide 1 by 642, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 642

Moving on to step 2:
When dividing 10 by 642, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 642

Advancing to step 3:
100 divided by 642 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 100 to get 100.
Fetch the next digit (8) from the dividend, attach it to 100 and continue: 1008 / 642

Moving on to step 4:
642 can be fit into 1008 1 times, resulting in a remainder of 366.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 642 from 1008 and we're left with 366.
Include the next digit (7) from the dividend after 366, then repeat: 3667 / 642

On to step 5:
642 can be fit into 3667 5 times, resulting in a remainder of 457.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 3210 from 3667 to get 457.
Bring next digit (6) of the dividend behind the 457 and repeat the process: 4576 / 642

Step 6:
642 goes into 4576 7 times with a remainder of 82.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
The remainder is 82 after subtracting 4494 from 4576.
Bring next digit (7) of the dividend behind the 82 and repeat the process: 827 / 642

Going ahead to step 7:
642 goes into 827 1 times with a remainder of 185.
Write down 1 as next digit of the result. 
Result so far: 1571.0
If we subtract 642 from 827, we get 185.
Take the next digit (6) from the dividend and append it to 185, then repeat: 1856 / 642

On to step 8:
If we divide 1856 by 642, we get 2 and a remainder of 572.
Use 2 as the next digit of our solution. 
Result so far: 15712.0
Deduct 1284 from 1856 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 9:
5720 divided by 642 is 8 with a remainder of 584.
Record the quotient 8 as the next digit in the result. 
Result so far: 15712.8
Subtracting 5136 from 5720 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 10:
If we divide 5840 by 642, we get 9 and a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 15712.89
Subtracting 5778 from 5840 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
If we divide 620 by 642, we get 0 and a remainder of 620.
The number 0 becomes the next digit in our result. 
Result so far: 15712.89
Subtract 0 from 620 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 12:
If we divide 6200 by 642, we get 9 and a remainder of 422.
Use 9 as the next digit of our solution. 
Result so far: 15712.8909
The remainder is 422 after subtracting 5778 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 13:
If we divide 4220 by 642, we get 6 and a remainder of 368.
Record the quotient 6 as the next digit in the result. 
Result so far: 15712.89096
If we subtract 3852 from 4220, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 14:
642 can be fit into 3680 5 times, resulting in a remainder of 470.
Use 5 as the next digit of our solution. 
Result so far: 15712.890965
Subtract 3210 from 3680 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 15:
If we divide 4700 by 642, we get 7 and a remainder of 206.
The next digit of our result is 7. 
Result so far: 15712.8909657
Subtracting 4494 from 4700 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 16:
When dividing 2060 by 642, we get 3 with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 15712.89096573
Deduct 1926 from 2060 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

In conclusion, the division gives 15712.89096573 with a balance of 1.34e-07.
