Let's divide 870784 by 87
We want to divide 870784 by 87.

Step 1:
87 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 87

Advancing to step 2:
The number 87 fits into 87 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 87 from 87, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 87

Let's proceed to step 3:
87 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 87

Let's proceed to step 4:
If we divide 7 by 87, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 87

On to step 5:
78 divided by 87 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 1000.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 87

On to step 6:
If we divide 784 by 87, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 10009.0
Subtracting 783 from 784 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
87 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 10009.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
87 can be fit into 100 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 10009.01
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
87 can be fit into 130 1 times, resulting in a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 10009.011
If we subtract 87 from 130, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Our division results in 10009.011 with a remaining 0.0043.
