8442578 divided by 487 
We want to divide 8442578 by 487.

Let's proceed to step 1:
When dividing 8 by 487, we get 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.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 487

Step 2:
487 goes into 84 0 times with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 487

Going ahead to step 3:
The number 487 fits into 844 1 times, leaving a remainder of 357.
The next digit of our result is 1. 
Result so far: 1.0
If we take 487 away from 844, we end up with 357.
Take the next digit (2) from the dividend and append it to 357, then repeat: 3572 / 487

Let's proceed to step 4:
If we divide 3572 by 487, we get 7 and a remainder of 163.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 163 after subtracting 3409 from 3572.
Include the next digit (5) from the dividend after 163, then repeat: 1635 / 487

Let's proceed to step 5:
487 goes into 1635 3 times with a remainder of 174.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
Subtract 1461 from 1635 to get 174.
Include the next digit (7) from the dividend after 174, then repeat: 1747 / 487

Step 6:
487 goes into 1747 3 times with a remainder of 286.
Put 3 as the next digit of the answer. 
Result so far: 1733.0
If we subtract 1461 from 1747, we get 286.
Take the next digit (8) from the dividend and append it to 286, then repeat: 2868 / 487

On to step 7:
If we divide 2868 by 487, we get 5 and a remainder of 433.
Use 5 as the next digit of our solution. 
Result so far: 17335.0
Subtract 2435 from 2868 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 8:
When dividing 4330 by 487, we get 8 with a remainder of 434.
Use 8 as the next digit of our solution. 
Result so far: 17335.8
The remainder is 434 after subtracting 3896 from 4330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 9:
487 goes into 4340 8 times with a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 17335.88
Subtract 3896 from 4340 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

The final result is 17335.88 with a remainder of 0.444.
