87263363 divided by 870 
We want to figure out the number of times 87263363 can be divided by 870.

On to step 1:
If we divide 8 by 870, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 870

On to step 2:
870 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Bring next digit (2) of the dividend behind the 87 and repeat the process: 872 / 870

Moving on to step 3:
872 divided by 870 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 870 from 872 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 870

Going ahead to step 4:
The number 870 fits into 26 0 times, leaving a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 26, we get 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 870

Let's proceed to step 5:
If we divide 263 by 870, we get 0 and a remainder of 263.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we take 0 away from 263, we end up with 263.
Include the next digit (3) from the dividend after 263, then repeat: 2633 / 870

Going ahead to step 6:
The number 870 fits into 2633 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 1003.0
Subtract 2610 from 2633 to get 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 870

Let's proceed to step 7:
236 divided by 870 is 0 with a remainder of 236.
The next digit of our result is 0. 
Result so far: 10030.0
The remainder is 236 after subtracting 0 from 236.
Bring next digit (3) of the dividend behind the 236 and repeat the process: 2363 / 870

Step 8:
The number 870 fits into 2363 2 times, leaving a remainder of 623.
Record the quotient 2 as the next digit in the result. 
Result so far: 100302.0
The remainder is 623 after subtracting 1740 from 2363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Step 9:
870 can be fit into 6230 7 times, resulting in a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 100302.7
Deduct 6090 from 6230 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
870 goes into 1400 1 times with a remainder of 530.
Write down 1 as next digit of the result. 
Result so far: 100302.71
Deduct 870 from 1400 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 11:
5300 divided by 870 is 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 100302.716
Subtract 5220 from 5300 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 870 is 0 with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 100302.716
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 13:
If we divide 8000 by 870, we get 9 and a remainder of 170.
The number 9 becomes the next digit in our result. 
Result so far: 100302.71609
Subtract 7830 from 8000 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
The number 870 fits into 1700 1 times, leaving a remainder of 830.
Record the quotient 1 as the next digit in the result. 
Result so far: 100302.716091
Subtract 870 from 1700 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Moving on to step 15:
The number 870 fits into 8300 9 times, leaving a remainder of 470.
Write down 9 as next digit of the result. 
Result so far: 100302.7160919
The remainder is 470 after subtracting 7830 from 8300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 16:
4700 divided by 870 is 5 with a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 100302.71609195
Deduct 4350 from 4700 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

In conclusion, the division gives 100302.71609195 with a balance of 3.5e-07.
