We divide 8504518 by 870
We want to divide 8504518 by 870.

Step 1:
870 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 870

Step 2:
85 divided by 870 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 870

Let's proceed to step 3:
870 goes into 850 0 times with a remainder of 850.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 850, we end up with 850.
Grab the next digit (4) from the dividend, add it to 850, then carry on: 8504 / 870

Step 4:
870 goes into 8504 9 times with a remainder of 674.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7830 from 8504, we get 674.
Take the next digit (5) from the dividend and append it to 674, then repeat: 6745 / 870

Advancing to step 5:
870 can be fit into 6745 7 times, resulting in a remainder of 655.
Put 7 as the next digit of the answer. 
Result so far: 97.0
The remainder is 655 after subtracting 6090 from 6745.
Append the next digit (1) from the dividend to 655 and continue with: 6551 / 870

Advancing to step 6:
When dividing 6551 by 870, we get 7 with a remainder of 461.
Record the quotient 7 as the next digit in the result. 
Result so far: 977.0
If we subtract 6090 from 6551, we get 461.
Include the next digit (8) from the dividend after 461, then repeat: 4618 / 870

Step 7:
870 can be fit into 4618 5 times, resulting in a remainder of 268.
Use 5 as the next digit of our solution. 
Result so far: 9775.0
Deduct 4350 from 4618 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 8:
The number 870 fits into 2680 3 times, leaving a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 9775.3
The remainder is 70 after subtracting 2610 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
If we divide 700 by 870, we get 0 and a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 9775.3
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 10:
870 can be fit into 7000 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 9775.308
Subtract 6960 from 7000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
If we divide 400 by 870, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 9775.308
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
The number 870 fits into 4000 4 times, leaving a remainder of 520.
The next digit of our result is 4. 
Result so far: 9775.30804
Subtracting 3480 from 4000 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 13:
If we divide 5200 by 870, we get 5 and a remainder of 850.
The number 5 becomes the next digit in our result. 
Result so far: 9775.308045
If we subtract 4350 from 5200, we get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Advancing to step 14:
The number 870 fits into 8500 9 times, leaving a remainder of 670.
Record the quotient 9 as the next digit in the result. 
Result so far: 9775.3080459
Deduct 7830 from 8500 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 15:
When dividing 6700 by 870, we get 7 with a remainder of 610.
Write down 7 as next digit of the result. 
Result so far: 9775.30804597
Subtract 6090 from 6700 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

The final result is 9775.30804597 with a remainder of 6.1e-07.
