We look at the division of 21627809 by 306 
We're looking to find how many times 306 goes into 21627809.

Going ahead to step 1:
When dividing 2 by 306, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 306

Let's proceed to step 2:
When dividing 21 by 306, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 306

Moving on to step 3:
When dividing 216 by 306, we get 0 with a remainder of 216.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Fetch the next digit (2) from the dividend, attach it to 216 and continue: 2162 / 306

Let's proceed to step 4:
306 can be fit into 2162 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 2142 from 2162 leaves us with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 306

Going ahead to step 5:
306 goes into 207 0 times with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 70.0
The remainder is 207 after subtracting 0 from 207.
Include the next digit (8) from the dividend after 207, then repeat: 2078 / 306

Step 6:
306 can be fit into 2078 6 times, resulting in a remainder of 242.
The number 6 becomes the next digit in our result. 
Result so far: 706.0
Subtract 1836 from 2078 to get 242.
Include the next digit (0) from the dividend after 242, then repeat: 2420 / 306

Moving on to step 7:
2420 divided by 306 is 7 with a remainder of 278.
Write down 7 as next digit of the result. 
Result so far: 7067.0
Subtract 2142 from 2420 to get 278.
Take the next digit (9) from the dividend and append it to 278, then repeat: 2789 / 306

Going ahead to step 8:
306 goes into 2789 9 times with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 70679.0
Deduct 2754 from 2789 and we're left 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.

Moving on to step 9:
If we divide 350 by 306, we get 1 and a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 70679.1
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
The number 306 fits into 440 1 times, leaving a remainder of 134.
Put 1 as the next digit of the answer. 
Result so far: 70679.11
Deduct 306 from 440 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 70679.11 and a remainder of 0.134.
