388992 divided by 28 
We're looking to find how many times 28 goes into 388992.

On to step 1:
The number 28 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 28

Moving on to step 2:
The number 28 fits into 38 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 28 away from 38, we end up with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 28

Advancing to step 3:
When dividing 108 by 28, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 84 away from 108, we end up with 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 28

Step 4:
The number 28 fits into 249 8 times, leaving a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we subtract 224 from 249, we get 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 28

On to step 5:
The number 28 fits into 259 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 1389.0
Subtracting 252 from 259 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 28

Step 6:
28 goes into 72 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 13892.0
If we subtract 56 from 72, we 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.

Advancing to step 7:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 13892.5
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.

Step 8:
200 divided by 28 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 13892.57
Subtract 196 from 200 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 9:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 13892.571
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 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13892.5714
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.

On to step 11:
If we divide 80 by 28, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 13892.57142
Subtracting 56 from 80 leaves us 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.

Going ahead to step 12:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 13892.571428
Subtracting 224 from 240 leaves us 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.

Let's proceed to step 13:
28 goes into 160 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 13892.5714285
Subtracting 140 from 160 leaves us 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.

Step 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 13892.57142857
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.

After the division, we end up with 13892.57142857 and a remainder of 4e-09.
