878136 ÷ 87 
Let's see how many times 87 fits into 878136.

Step 1:
87 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 87

Step 2:
87 can be fit into 87 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 87 away from 87, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 87

On to step 3:
If we divide 8 by 87, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 87

Moving on to step 4:
81 divided by 87 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 87

On to step 5:
813 divided by 87 is 9 with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 1009.0
Subtracting 783 from 813 leaves us with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 87

Let's proceed to step 6:
When dividing 306 by 87, we get 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 10093.0
If we take 261 away from 306, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 87 fits into 450 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 10093.5
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
87 can be fit into 150 1 times, resulting in a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 10093.51
The remainder is 63 after subtracting 87 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
87 can be fit into 630 7 times, resulting in a remainder of 21.
The next digit of our result is 7. 
Result so far: 10093.517
Subtract 609 from 630 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 10:
The number 87 fits into 210 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 10093.5172
Subtract 174 from 210 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
360 divided by 87 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 10093.51724
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
When dividing 120 by 87, we get 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 10093.517241
The remainder is 33 after subtracting 87 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
The number 87 fits into 330 3 times, leaving a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 10093.5172413
Subtracting 261 from 330 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 14:
87 goes into 690 7 times with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 10093.51724137
Deduct 609 from 690 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 10093.51724137, with a leftover of 8.1e-08.
