We divide 390589 by 28
We're looking to find how many times 28 goes into 390589.

Step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 28

Step 2:
39 divided by 28 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 28 from 39 and we're left with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 28

On to step 3:
When dividing 110 by 28, we get 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 26 after subtracting 84 from 110.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 28

Let's proceed to step 4:
When dividing 265 by 28, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Deduct 252 from 265 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 28

Going ahead to step 5:
If we divide 138 by 28, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 1394.0
Deduct 112 from 138 and we're left with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 28

On to step 6:
The number 28 fits into 269 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 13949.0
Deduct 252 from 269 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
28 goes into 170 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 13949.6
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 28 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 13949.6
If we take 0 away from 20, we end up 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.

Let's proceed to step 9:
When dividing 200 by 28, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 13949.607
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.

On to step 10:
28 goes into 40 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 13949.6071
The remainder is 12 after subtracting 28 from 40.
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 11:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 13949.60714
If we subtract 112 from 120, we 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.

Going ahead to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 13949.607142
Subtract 56 from 80 to get 24.
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 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: 13949.6071428
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.

On to step 14:
160 divided by 28 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 13949.60714285
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.

In conclusion, the division gives 13949.60714285 with a balance of 2e-08.
