We look at the division of 21164515 by 706 
We want to divide 21164515 by 706.

Let's proceed to step 1:
706 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
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 / 706

Advancing to step 2:
If we divide 21 by 706, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 706

Advancing to step 3:
If we divide 211 by 706, we get 0 and a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Take the next digit (6) from the dividend and append it to 211, then repeat: 2116 / 706

Moving on to step 4:
706 goes into 2116 2 times with a remainder of 704.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1412 from 2116, we get 704.
Take the next digit (4) from the dividend and append it to 704, then repeat: 7044 / 706

Step 5:
7044 divided by 706 is 9 with a remainder of 690.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 6354 from 7044 and we're left with 690.
Take the next digit (5) from the dividend and append it to 690, then repeat: 6905 / 706

On to step 6:
706 goes into 6905 9 times with a remainder of 551.
Write down 9 as next digit of the result. 
Result so far: 299.0
If we take 6354 away from 6905, we end up with 551.
Include the next digit (1) from the dividend after 551, then repeat: 5511 / 706

Advancing to step 7:
706 can be fit into 5511 7 times, resulting in a remainder of 569.
Record the quotient 7 as the next digit in the result. 
Result so far: 2997.0
Subtracting 4942 from 5511 leaves us with 569.
Bring next digit (5) of the dividend behind the 569 and repeat the process: 5695 / 706

Going ahead to step 8:
When dividing 5695 by 706, we get 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 29978.0
Subtracting 5648 from 5695 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
706 can be fit into 470 0 times, resulting in a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 29978.0
The remainder is 470 after subtracting 0 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 10:
4700 divided by 706 is 6 with a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 29978.06
Subtract 4236 from 4700 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 11:
4640 divided by 706 is 6 with a remainder of 404.
The number 6 becomes the next digit in our result. 
Result so far: 29978.066
The remainder is 404 after subtracting 4236 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

After the division, we end up with 29978.066 and a remainder of 0.0404.
