386388 divided by 28 
Let's see how many times 28 fits into 386388.

On to step 1:
3 divided by 28 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 28

Going ahead to step 2:
If we divide 38 by 28, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 28 from 38 to get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 28

Let's proceed to step 3:
When dividing 106 by 28, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 84 from 106 and we're left with 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 28

On to step 4:
223 divided by 28 is 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we subtract 196 from 223, we get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 28

Moving on to step 5:
If we divide 278 by 28, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1379.0
If we take 252 away from 278, we end up with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 28

Moving on to step 6:
The number 28 fits into 268 9 times, leaving a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 13799.0
If we take 252 away from 268, 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.

Let's proceed to step 7:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 13799.5
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.

Going ahead to step 8:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 13799.57
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.

Advancing to step 9:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 13799.571
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.

Advancing to step 10:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13799.5714
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.

Advancing to step 11:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 13799.57142
If we take 56 away from 80, we end up 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.

Step 12:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 13799.571428
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.

Advancing to step 13:
When dividing 160 by 28, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 13799.5714285
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 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 13799.57142857
If we subtract 196 from 200, we 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.

After the division, we end up with 13799.57142857 and a remainder of 4e-09.
