We're dividing 20824583 by 870 
We're looking to find how many times 870 goes into 20824583.

On to step 1:
The number 870 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 870

Let's proceed to step 2:
870 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 870

Let's proceed to step 3:
208 divided by 870 is 0 with a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 208, we get 208.
Grab the next digit (2) from the dividend, add it to 208, then carry on: 2082 / 870

On to step 4:
870 can be fit into 2082 2 times, resulting in a remainder of 342.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1740 from 2082 and we're left with 342.
Fetch the next digit (4) from the dividend, attach it to 342 and continue: 3424 / 870

On to step 5:
870 goes into 3424 3 times with a remainder of 814.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 2610 away from 3424, we end up with 814.
Fetch the next digit (5) from the dividend, attach it to 814 and continue: 8145 / 870

Advancing to step 6:
If we divide 8145 by 870, we get 9 and a remainder of 315.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
Subtracting 7830 from 8145 leaves us with 315.
Bring next digit (8) of the dividend behind the 315 and repeat the process: 3158 / 870

Moving on to step 7:
3158 divided by 870 is 3 with a remainder of 548.
The number 3 becomes the next digit in our result. 
Result so far: 2393.0
Subtracting 2610 from 3158 leaves us with 548.
Include the next digit (3) from the dividend after 548, then repeat: 5483 / 870

Step 8:
870 can be fit into 5483 6 times, resulting in a remainder of 263.
Write down 6 as next digit of the result. 
Result so far: 23936.0
Subtract 5220 from 5483 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 9:
870 can be fit into 2630 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 23936.3
Subtracting 2610 from 2630 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
870 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 23936.3
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
The number 870 fits into 2000 2 times, leaving a remainder of 260.
The number 2 becomes the next digit in our result. 
Result so far: 23936.302
Subtracting 1740 from 2000 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 12:
When dividing 2600 by 870, we get 2 with a remainder of 860.
The next digit of our result is 2. 
Result so far: 23936.3022
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.

The final outcome is 23936.3022, with a leftover of 0.0086.
