We're dividing 21294455 by 710 
We want to divide 21294455 by 710.

On to step 1:
If we divide 2 by 710, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 710

Moving on to step 2:
21 divided by 710 is 0 with 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.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 710

Moving on to step 3:
When dividing 212 by 710, we get 0 with a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 212, we get 212.
Fetch the next digit (9) from the dividend, attach it to 212 and continue: 2129 / 710

On to step 4:
710 goes into 2129 2 times with a remainder of 709.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 709 after subtracting 1420 from 2129.
Include the next digit (4) from the dividend after 709, then repeat: 7094 / 710

Let's proceed to step 5:
If we divide 7094 by 710, we get 9 and a remainder of 704.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 6390 away from 7094, we end up with 704.
Bring next digit (4) of the dividend behind the 704 and repeat the process: 7044 / 710

Moving on to step 6:
710 goes into 7044 9 times with a remainder of 654.
The next digit of our result is 9. 
Result so far: 299.0
Subtracting 6390 from 7044 leaves us with 654.
Include the next digit (5) from the dividend after 654, then repeat: 6545 / 710

Let's proceed to step 7:
6545 divided by 710 is 9 with a remainder of 155.
Write down 9 as next digit of the result. 
Result so far: 2999.0
Subtract 6390 from 6545 to get 155.
Include the next digit (5) from the dividend after 155, then repeat: 1555 / 710

Moving on to step 8:
The number 710 fits into 1555 2 times, leaving a remainder of 135.
Write down 2 as next digit of the result. 
Result so far: 29992.0
Deduct 1420 from 1555 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
The number 710 fits into 1350 1 times, leaving a remainder of 640.
Put 1 as the next digit of the answer. 
Result so far: 29992.1
If we take 710 away from 1350, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 10:
The number 710 fits into 6400 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 29992.19
Subtract 6390 from 6400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
When dividing 100 by 710, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 29992.19
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
710 can be fit into 1000 1 times, resulting in a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 29992.1901
The remainder is 290 after subtracting 710 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 13:
If we divide 2900 by 710, we get 4 and a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 29992.19014
Subtracting 2840 from 2900 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
710 goes into 600 0 times with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 29992.19014
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 15:
When dividing 6000 by 710, we get 8 with a remainder of 320.
The number 8 becomes the next digit in our result. 
Result so far: 29992.1901408
The remainder is 320 after subtracting 5680 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 16:
710 goes into 3200 4 times with a remainder of 360.
The next digit of our result is 4. 
Result so far: 29992.19014084
If we subtract 2840 from 3200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 29992.19014084 and a remainder of 3.6e-07.
