21307326 divided by 839 
We want to figure out the number of times 21307326 can be divided by 839.

On to step 1:
The number 839 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 839

Moving on to step 2:
When dividing 21 by 839, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 839

Advancing to step 3:
213 divided by 839 is 0 with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Grab the next digit (0) from the dividend, add it to 213, then carry on: 2130 / 839

Step 4:
When dividing 2130 by 839, we get 2 with a remainder of 452.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1678 from 2130 and we're left with 452.
Append the next digit (7) from the dividend to 452 and continue with: 4527 / 839

On to step 5:
839 can be fit into 4527 5 times, resulting in a remainder of 332.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 332 after subtracting 4195 from 4527.
Take the next digit (3) from the dividend and append it to 332, then repeat: 3323 / 839

Going ahead to step 6:
If we divide 3323 by 839, we get 3 and a remainder of 806.
Record the quotient 3 as the next digit in the result. 
Result so far: 253.0
The remainder is 806 after subtracting 2517 from 3323.
Fetch the next digit (2) from the dividend, attach it to 806 and continue: 8062 / 839

Advancing to step 7:
The number 839 fits into 8062 9 times, leaving a remainder of 511.
Use 9 as the next digit of our solution. 
Result so far: 2539.0
If we subtract 7551 from 8062, we get 511.
Bring next digit (6) of the dividend behind the 511 and repeat the process: 5116 / 839

Moving on to step 8:
If we divide 5116 by 839, we get 6 and a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 25396.0
Subtract 5034 from 5116 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
When dividing 820 by 839, we get 0 with a remainder of 820.
Put 0 as the next digit of the answer. 
Result so far: 25396.0
Deduct 0 from 820 and we're left with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Step 10:
839 goes into 8200 9 times with a remainder of 649.
Record the quotient 9 as the next digit in the result. 
Result so far: 25396.09
If we take 7551 away from 8200, we end up with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 11:
839 can be fit into 6490 7 times, resulting in a remainder of 617.
Write down 7 as next digit of the result. 
Result so far: 25396.097
Subtracting 5873 from 6490 leaves us with 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Advancing to step 12:
If we divide 6170 by 839, we get 7 and a remainder of 297.
Put 7 as the next digit of the answer. 
Result so far: 25396.0977
If we subtract 5873 from 6170, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

In conclusion, the division gives 25396.0977 with a balance of 0.00297.
