We're dividing 879402 by 87 
We're looking to find how many times 87 goes into 879402.

Step 1:
When dividing 8 by 87, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 87

Moving on to step 2:
If we divide 87 by 87, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 87 from 87 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 87

Going ahead to step 3:
87 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 9, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 87

Advancing to step 4:
If we divide 94 by 87, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 87 from 94 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 87

Advancing to step 5:
87 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1010.0
The remainder is 70 after subtracting 0 from 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 87

Moving on to step 6:
87 can be fit into 702 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 10108.0
If we subtract 696 from 702, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 87, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10108.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
When dividing 600 by 87, we get 6 with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 10108.06
The remainder is 78 after subtracting 522 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
87 goes into 780 8 times with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 10108.068
If we take 696 away from 780, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
840 divided by 87 is 9 with a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 10108.0689
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
87 goes into 570 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 10108.06896
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
If we divide 480 by 87, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 10108.068965
If we take 435 away from 480, 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.

Let's proceed to step 13:
87 goes into 450 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 10108.0689655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 10108.0689655 and a remainder of 1.5e-07.
