We look at the division of 339450 by 28 
We want to divide 339450 by 28.

On to step 1:
28 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 28

On to step 2:
28 goes into 33 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 5 after subtracting 28 from 33.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 28

Going ahead to step 3:
If we divide 59 by 28, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 56 from 59 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 28

Let's proceed to step 4:
28 can be fit into 34 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtracting 28 from 34 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 28

Going ahead to step 5:
28 goes into 65 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 1212.0
The remainder is 9 after subtracting 56 from 65.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 28

Going ahead to step 6:
90 divided by 28 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 12123.0
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 28, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 12123.2
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.

Let's proceed to step 8:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 12123.21
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.

Let's proceed to step 9:
If we divide 120 by 28, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 12123.214
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
28 goes into 80 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 12123.2142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 12123.21428
Subtract 224 from 240 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.

Moving on to step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 12123.214285
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.

Step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 12123.2142857
Deduct 196 from 200 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.

On to step 14:
If we divide 40 by 28, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 12123.21428571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 12123.21428571 with a remainder of 1.2e-08.
