21834211 ÷ 836 
We want to divide 21834211 by 836.

Let's proceed to step 1:
2 divided by 836 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 836

Going ahead to step 2:
When dividing 21 by 836, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 836

Advancing to step 3:
If we divide 218 by 836, we get 0 and a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 218 to get 218.
Include the next digit (3) from the dividend after 218, then repeat: 2183 / 836

Step 4:
836 can be fit into 2183 2 times, resulting in a remainder of 511.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 511 after subtracting 1672 from 2183.
Include the next digit (4) from the dividend after 511, then repeat: 5114 / 836

Advancing to step 5:
The number 836 fits into 5114 6 times, leaving a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 98 after subtracting 5016 from 5114.
Include the next digit (2) from the dividend after 98, then repeat: 982 / 836

Step 6:
When dividing 982 by 836, we get 1 with a remainder of 146.
Write down 1 as next digit of the result. 
Result so far: 261.0
The remainder is 146 after subtracting 836 from 982.
Bring next digit (1) of the dividend behind the 146 and repeat the process: 1461 / 836

Step 7:
The number 836 fits into 1461 1 times, leaving a remainder of 625.
The next digit of our result is 1. 
Result so far: 2611.0
Subtracting 836 from 1461 leaves us with 625.
Fetch the next digit (1) from the dividend, attach it to 625 and continue: 6251 / 836

Let's proceed to step 8:
If we divide 6251 by 836, we get 7 and a remainder of 399.
Write down 7 as next digit of the result. 
Result so far: 26117.0
If we subtract 5852 from 6251, we get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 9:
When dividing 3990 by 836, we get 4 with a remainder of 646.
Write down 4 as next digit of the result. 
Result so far: 26117.4
The remainder is 646 after subtracting 3344 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 10:
The number 836 fits into 6460 7 times, leaving a remainder of 608.
Write down 7 as next digit of the result. 
Result so far: 26117.47
Subtracting 5852 from 6460 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 11:
When dividing 6080 by 836, we get 7 with a remainder of 228.
Put 7 as the next digit of the answer. 
Result so far: 26117.477
If we subtract 5852 from 6080, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

In conclusion, the division gives 26117.477 with a balance of 0.0228.
