873916 divided by 87 
We're looking to find how many times 87 goes into 873916.

Advancing to step 1:
8 divided by 87 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 87

Let's proceed to step 2:
When dividing 87 by 87, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 87 away from 87, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 87

Step 3:
3 divided by 87 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 87

Step 4:
87 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 39, we end up with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 87

Let's proceed to step 5:
87 can be fit into 391 4 times, resulting in a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 1004.0
Subtracting 348 from 391 leaves us with 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 87

Let's proceed to step 6:
The number 87 fits into 436 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 10045.0
The remainder is 1 after subtracting 435 from 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 87, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10045.0
If we subtract 0 from 10, we get 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.
Put 1 as the next digit of the answer. 
Result so far: 10045.01
Deduct 87 from 100 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
87 goes into 130 1 times with a remainder of 43.
The next digit of our result is 1. 
Result so far: 10045.011
If we take 87 away from 130, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 10045.011 with a remainder of 0.0043.
