We're dividing 21593708 by 839 
We want to divide 21593708 by 839.

Moving on to step 1:
When dividing 2 by 839, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 839

Going ahead to step 2:
The number 839 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 839

Going ahead to step 3:
When dividing 215 by 839, we get 0 with a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 215 leaves us with 215.
Append the next digit (9) from the dividend to 215 and continue with: 2159 / 839

Advancing to step 4:
2159 divided by 839 is 2 with a remainder of 481.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1678 from 2159 leaves us with 481.
Append the next digit (3) from the dividend to 481 and continue with: 4813 / 839

Moving on to step 5:
4813 divided by 839 is 5 with a remainder of 618.
The next digit of our result is 5. 
Result so far: 25.0
If we take 4195 away from 4813, we end up with 618.
Bring next digit (7) of the dividend behind the 618 and repeat the process: 6187 / 839

Going ahead to step 6:
If we divide 6187 by 839, we get 7 and a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
Subtract 5873 from 6187 to get 314.
Include the next digit (0) from the dividend after 314, then repeat: 3140 / 839

Let's proceed to step 7:
The number 839 fits into 3140 3 times, leaving a remainder of 623.
Write down 3 as next digit of the result. 
Result so far: 2573.0
If we take 2517 away from 3140, we end up with 623.
Take the next digit (8) from the dividend and append it to 623, then repeat: 6238 / 839

Moving on to step 8:
6238 divided by 839 is 7 with a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 25737.0
If we take 5873 away from 6238, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 9:
If we divide 3650 by 839, we get 4 and a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 25737.4
Subtracting 3356 from 3650 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
The number 839 fits into 2940 3 times, leaving a remainder of 423.
The next digit of our result is 3. 
Result so far: 25737.43
The remainder is 423 after subtracting 2517 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 11:
839 goes into 4230 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 25737.435
If we take 4195 away from 4230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
350 divided by 839 is 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 25737.435
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 13:
When dividing 3500 by 839, we get 4 with a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 25737.43504
If we subtract 3356 from 3500, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 14:
The number 839 fits into 1440 1 times, leaving a remainder of 601.
The next digit of our result is 1. 
Result so far: 25737.435041
If we take 839 away from 1440, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Going ahead to step 15:
If we divide 6010 by 839, we get 7 and a remainder of 137.
The next digit of our result is 7. 
Result so far: 25737.4350417
The remainder is 137 after subtracting 5873 from 6010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 16:
The number 839 fits into 1370 1 times, leaving a remainder of 531.
Write down 1 as next digit of the result. 
Result so far: 25737.43504171
Subtracting 839 from 1370 leaves us with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

After the division, we end up with 25737.43504171 and a remainder of 5.31e-07.
