We look at the division of 21904396 by 839 
Let's see how many times 839 fits into 21904396.

Step 1:
If we divide 2 by 839, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 839

Going ahead 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
Subtract 0 from 21 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 839

Let's proceed to step 3:
If we divide 219 by 839, we get 0 and a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Include the next digit (0) from the dividend after 219, then repeat: 2190 / 839

Let's proceed to step 4:
839 goes into 2190 2 times with a remainder of 512.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1678 from 2190 to get 512.
Append the next digit (4) from the dividend to 512 and continue with: 5124 / 839

Advancing to step 5:
If we divide 5124 by 839, we get 6 and a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 90 after subtracting 5034 from 5124.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 839

Going ahead to step 6:
If we divide 903 by 839, we get 1 and a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 261.0
The remainder is 64 after subtracting 839 from 903.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 839

Moving on to step 7:
649 divided by 839 is 0 with a remainder of 649.
Write down 0 as next digit of the result. 
Result so far: 2610.0
If we take 0 away from 649, we end up with 649.
Bring next digit (6) of the dividend behind the 649 and repeat the process: 6496 / 839

Moving on to step 8:
839 can be fit into 6496 7 times, resulting in a remainder of 623.
The next digit of our result is 7. 
Result so far: 26107.0
If we subtract 5873 from 6496, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Step 9:
6230 divided by 839 is 7 with a remainder of 357.
Use 7 as the next digit of our solution. 
Result so far: 26107.7
Subtract 5873 from 6230 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 10:
The number 839 fits into 3570 4 times, leaving a remainder of 214.
Write down 4 as next digit of the result. 
Result so far: 26107.74
Subtracting 3356 from 3570 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 11:
If we divide 2140 by 839, we get 2 and a remainder of 462.
Use 2 as the next digit of our solution. 
Result so far: 26107.742
If we subtract 1678 from 2140, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 12:
4620 divided by 839 is 5 with a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 26107.7425
If we subtract 4195 from 4620, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 13:
4250 divided by 839 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 26107.74255
If we subtract 4195 from 4250, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 26107.74255 with a remaining 5.5e-05.
