We're dividing 27945 by 7 
Let's see how many times 7 fits into 27945.

Going ahead to step 1:
When dividing 2 by 7, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 7

Moving on to step 2:
7 can be fit into 27 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 21 from 27 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 7

On to step 3:
69 divided by 7 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 63 from 69 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 7

Advancing to step 4:
When dividing 64 by 7, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 399.0
The remainder is 1 after subtracting 63 from 64.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 7

Moving on to step 5:
15 divided by 7 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 3992.0
If we take 14 away from 15, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 3992.1
Deduct 7 from 10 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 7, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 3992.14
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 3992.142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3992.1428
Subtract 56 from 60 to 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.

Going ahead to step 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3992.14285
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 3992.142857
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 3992.1428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 3992.14285714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 3992.14285714 and a remainder of 2e-09.
