We're dividing 82455899 by 870 
Let's see how many times 870 fits into 82455899.

On to step 1:
The number 870 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 870

On to step 2:
82 divided by 870 is 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 870

On to step 3:
When dividing 824 by 870, we get 0 with a remainder of 824.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 824, we end up with 824.
Fetch the next digit (5) from the dividend, attach it to 824 and continue: 8245 / 870

Step 4:
870 can be fit into 8245 9 times, resulting in a remainder of 415.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 7830 away from 8245, we end up with 415.
Include the next digit (5) from the dividend after 415, then repeat: 4155 / 870

Let's proceed to step 5:
If we divide 4155 by 870, we get 4 and a remainder of 675.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 3480 away from 4155, we end up with 675.
Append the next digit (8) from the dividend to 675 and continue with: 6758 / 870

Advancing to step 6:
870 goes into 6758 7 times with a remainder of 668.
Put 7 as the next digit of the answer. 
Result so far: 947.0
Subtract 6090 from 6758 to get 668.
Take the next digit (9) from the dividend and append it to 668, then repeat: 6689 / 870

On to step 7:
870 can be fit into 6689 7 times, resulting in a remainder of 599.
Put 7 as the next digit of the answer. 
Result so far: 9477.0
Subtract 6090 from 6689 to get 599.
Bring next digit (9) of the dividend behind the 599 and repeat the process: 5999 / 870

Let's proceed to step 8:
870 can be fit into 5999 6 times, resulting in a remainder of 779.
Record the quotient 6 as the next digit in the result. 
Result so far: 94776.0
If we subtract 5220 from 5999, we get 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

On to step 9:
When dividing 7790 by 870, we get 8 with a remainder of 830.
Record the quotient 8 as the next digit in the result. 
Result so far: 94776.8
Deduct 6960 from 7790 and we're left with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Moving on to step 10:
When dividing 8300 by 870, we get 9 with a remainder of 470.
Write down 9 as next digit of the result. 
Result so far: 94776.89
Deduct 7830 from 8300 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 11:
4700 divided by 870 is 5 with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 94776.895
If we take 4350 away from 4700, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 12:
When dividing 3500 by 870, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 94776.8954
Subtract 3480 from 3500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
When dividing 200 by 870, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 94776.8954
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 14:
870 goes into 2000 2 times with a remainder of 260.
The number 2 becomes the next digit in our result. 
Result so far: 94776.895402
If we subtract 1740 from 2000, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 15:
870 goes into 2600 2 times with a remainder of 860.
The next digit of our result is 2. 
Result so far: 94776.8954022
Subtract 1740 from 2600 to get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

After the division, we end up with 94776.8954022 and a remainder of 8.6e-06.
