Let's divide 399150 by 28
We want to divide 399150 by 28.

Going ahead to step 1:
28 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 28

On to step 2:
39 divided by 28 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 28 from 39 and we're left with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 28

Advancing to step 3:
28 goes into 119 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 112 from 119 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 28

On to step 4:
The number 28 fits into 71 2 times, leaving a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 56 from 71 to get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 28

On to step 5:
28 goes into 155 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1425.0
If we take 140 away from 155, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 28

Moving on to step 6:
When dividing 150 by 28, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 14255.0
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 28 fits into 100 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 14255.3
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 14255.35
Subtract 140 from 160 to 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.

Moving on to step 9:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 14255.357
The remainder is 4 after subtracting 196 from 200.
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 10:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 14255.3571
Subtracting 28 from 40 leaves us 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.

Advancing to step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 14255.35714
Subtract 112 from 120 to get 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:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 14255.357142
Deduct 56 from 80 and we're left with 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:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 14255.3571428
Deduct 224 from 240 and we're left 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.

Moving on to step 14:
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: 14255.35714285
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.

Our division results in 14255.35714285 with a remaining 2e-08.
