We're dividing 393830 by 28 
We want to divide 393830 by 28.

On to step 1:
When dividing 3 by 28, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 28

On to step 2:
28 goes into 39 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 28 from 39, we get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 28

Moving on to step 3:
28 can be fit into 113 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 1 after subtracting 112 from 113.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 28

Moving on to step 4:
When dividing 18 by 28, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
If we subtract 0 from 18, we get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 28

Step 5:
If we divide 183 by 28, we get 6 and a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 1406.0
If we take 168 away from 183, we end up with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 28

On to step 6:
150 divided by 28 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 14065.0
If we take 140 away from 150, we end up with 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 7:
100 divided by 28 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 14065.3
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 14065.35
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 14065.357
If we take 196 away from 200, we end up 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 10:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 14065.3571
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 14065.35714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 14065.357142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
When dividing 240 by 28, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 14065.3571428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 14065.35714285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 14065.35714285, with a leftover of 2e-08.
