We're dividing 21803060 by 836 
Let's see how many times 836 fits into 21803060.

Let's proceed to step 1:
836 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 836

Let's proceed to step 2:
21 divided by 836 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 836

Moving on to step 3:
If we divide 218 by 836, we get 0 and a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 218 to get 218.
Fetch the next digit (0) from the dividend, attach it to 218 and continue: 2180 / 836

On to step 4:
When dividing 2180 by 836, we get 2 with a remainder of 508.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1672 from 2180 and we're left with 508.
Include the next digit (3) from the dividend after 508, then repeat: 5083 / 836

Moving on to step 5:
If we divide 5083 by 836, we get 6 and a remainder of 67.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtracting 5016 from 5083 leaves us with 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 836

Moving on to step 6:
670 divided by 836 is 0 with a remainder of 670.
Record the quotient 0 as the next digit in the result. 
Result so far: 260.0
Subtract 0 from 670 to get 670.
Append the next digit (6) from the dividend to 670 and continue with: 6706 / 836

Moving on to step 7:
6706 divided by 836 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 2608.0
The remainder is 18 after subtracting 6688 from 6706.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 836

Moving on to step 8:
The number 836 fits into 180 0 times, leaving a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 26080.0
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
1800 divided by 836 is 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 26080.2
Subtract 1672 from 1800 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
836 goes into 1280 1 times with a remainder of 444.
Record the quotient 1 as the next digit in the result. 
Result so far: 26080.21
If we subtract 836 from 1280, we 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.

On to step 11:
836 can be fit into 4440 5 times, resulting in a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 26080.215
Subtracting 4180 from 4440 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.

On to step 12:
836 goes into 2600 3 times with a remainder of 92.
Put 3 as the next digit of the answer. 
Result so far: 26080.2153
Deduct 2508 from 2600 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
If we divide 920 by 836, we get 1 and a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 26080.21531
The remainder is 84 after subtracting 836 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
840 divided by 836 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 26080.215311
Subtract 836 from 840 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 26080.215311 with a remainder of 4e-07.
