We're dividing 21030895 by 739 
Our goal is to divide 21030895 by 739.

Step 1:
If we divide 2 by 739, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 739

Let's proceed to step 2:
739 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 739

Step 3:
If we divide 210 by 739, we get 0 and a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Grab the next digit (3) from the dividend, add it to 210, then carry on: 2103 / 739

Moving on to step 4:
If we divide 2103 by 739, we get 2 and a remainder of 625.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1478 from 2103 leaves us with 625.
Include the next digit (0) from the dividend after 625, then repeat: 6250 / 739

Moving on to step 5:
739 can be fit into 6250 8 times, resulting in a remainder of 338.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 5912 from 6250 leaves us with 338.
Grab the next digit (8) from the dividend, add it to 338, then carry on: 3388 / 739

Step 6:
The number 739 fits into 3388 4 times, leaving a remainder of 432.
Put 4 as the next digit of the answer. 
Result so far: 284.0
If we subtract 2956 from 3388, we get 432.
Bring next digit (9) of the dividend behind the 432 and repeat the process: 4329 / 739

On to step 7:
739 can be fit into 4329 5 times, resulting in a remainder of 634.
Use 5 as the next digit of our solution. 
Result so far: 2845.0
If we take 3695 away from 4329, we end up with 634.
Append the next digit (5) from the dividend to 634 and continue with: 6345 / 739

Advancing to step 8:
The number 739 fits into 6345 8 times, leaving a remainder of 433.
The next digit of our result is 8. 
Result so far: 28458.0
Subtracting 5912 from 6345 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 9:
739 can be fit into 4330 5 times, resulting in a remainder of 635.
The next digit of our result is 5. 
Result so far: 28458.5
Subtracting 3695 from 4330 leaves us with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Let's proceed to step 10:
The number 739 fits into 6350 8 times, leaving a remainder of 438.
Record the quotient 8 as the next digit in the result. 
Result so far: 28458.58
If we subtract 5912 from 6350, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 11:
When dividing 4380 by 739, we get 5 with a remainder of 685.
Write down 5 as next digit of the result. 
Result so far: 28458.585
Deduct 3695 from 4380 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Going ahead to step 12:
If we divide 6850 by 739, we get 9 and a remainder of 199.
Record the quotient 9 as the next digit in the result. 
Result so far: 28458.5859
Subtracting 6651 from 6850 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 13:
739 can be fit into 1990 2 times, resulting in a remainder of 512.
Use 2 as the next digit of our solution. 
Result so far: 28458.58592
Deduct 1478 from 1990 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 14:
If we divide 5120 by 739, we get 6 and a remainder of 686.
The next digit of our result is 6. 
Result so far: 28458.585926
If we subtract 4434 from 5120, we get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Moving on to step 15:
The number 739 fits into 6860 9 times, leaving a remainder of 209.
Write down 9 as next digit of the result. 
Result so far: 28458.5859269
If we take 6651 away from 6860, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 16:
When dividing 2090 by 739, we get 2 with a remainder of 612.
Put 2 as the next digit of the answer. 
Result so far: 28458.58592692
Subtracting 1478 from 2090 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The final outcome is 28458.58592692, with a leftover of 6.12e-07.
