We're dividing 863465 by 87 
We're looking to find how many times 87 goes into 863465.

Let's proceed to step 1:
8 divided by 87 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 87

On to step 2:
The number 87 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 87

Step 3:
87 goes into 863 9 times with a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 783 from 863 to get 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 87

Going ahead to step 4:
87 goes into 804 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we subtract 783 from 804, we get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 87

On to step 5:
When dividing 216 by 87, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 992.0
If we take 174 away from 216, we end up with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 87

Let's proceed to step 6:
425 divided by 87 is 4 with a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 9924.0
Subtracting 348 from 425 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 7:
If we divide 770 by 87, we get 8 and a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 9924.8
Subtracting 696 from 770 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
If we divide 740 by 87, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 9924.88
The remainder is 44 after subtracting 696 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 9924.88, and the remainder is 0.044.
