We look at the division of 309973 by 27 
We want to figure out the number of times 309973 can be divided by 27.

Moving on to step 1:
If we divide 3 by 27, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 27

Going ahead to step 2:
30 divided by 27 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 27 from 30 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 27

Advancing to step 3:
If we divide 39 by 27, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 27 from 39 leaves us with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 27

Advancing to step 4:
27 goes into 129 4 times with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtract 108 from 129 to get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 27

Step 5:
27 can be fit into 217 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 1148.0
Subtract 216 from 217 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 27

Let's proceed to step 6:
When dividing 13 by 27, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 11480.0
Subtract 0 from 13 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
27 goes into 130 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 11480.4
If we subtract 108 from 130, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
220 divided by 27 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 11480.48
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 27, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 11480.481
Subtract 27 from 40 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
27 goes into 130 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 11480.4814
If we subtract 108 from 130, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
The number 27 fits into 220 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11480.48148
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
The number 27 fits into 40 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 11480.481481
Subtract 27 from 40 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
The number 27 fits into 130 4 times, leaving a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 11480.4814814
If we take 108 away from 130, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
The number 27 fits into 220 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 11480.48148148
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 11480.48148148 with a remaining 4e-09.
