150399 divided by 28 
We want to figure out the number of times 150399 can be divided by 28.

Going ahead to step 1:
28 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 28

Step 2:
The number 28 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 28

Advancing to step 3:
28 goes into 150 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 140 from 150 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 28

Going ahead to step 4:
28 can be fit into 103 3 times, resulting in a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtract 84 from 103 to get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 28

On to step 5:
When dividing 199 by 28, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 537.0
Subtract 196 from 199 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 28

Let's proceed to step 6:
When dividing 39 by 28, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 5371.0
If we subtract 28 from 39, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
28 can be fit into 110 3 times, resulting in a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 5371.3
If we take 84 away from 110, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
The number 28 fits into 260 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 5371.39
Deduct 252 from 260 and we're left 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.

Moving on to step 9:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 5371.392
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.

Advancing to step 10:
240 divided by 28 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 5371.3928
The remainder is 16 after subtracting 224 from 240.
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 11:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 5371.39285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 5371.392857
Subtracting 196 from 200 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 13:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 5371.3928571
If we take 28 away from 40, we end up 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.

Step 14:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 5371.39285714
If we take 112 away from 120, we end up 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.

After the division, we end up with 5371.39285714 and a remainder of 8e-09.
