389958 divided by 28 
We're looking to find how many times 28 goes into 389958.

Step 1:
When dividing 3 by 28, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 28

Step 2:
When dividing 38 by 28, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 10 after subtracting 28 from 38.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 28

Moving on to step 3:
The number 28 fits into 109 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 25 after subtracting 84 from 109.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 28

Advancing to step 4:
The number 28 fits into 259 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 139.0
Deduct 252 from 259 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 28

Going ahead to step 5:
When dividing 75 by 28, we get 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 1392.0
Subtract 56 from 75 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 28

Let's proceed to step 6:
28 can be fit into 198 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 13927.0
The remainder is 2 after subtracting 196 from 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
28 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13927.0
Deduct 0 from 20 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.

Let's proceed to step 8:
28 goes into 200 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 13927.07
Deduct 196 from 200 and we're left 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.

Step 9:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 13927.071
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 10:
When dividing 120 by 28, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 13927.0714
Deduct 112 from 120 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.

Let's proceed to step 11:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 13927.07142
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.

Advancing to step 12:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 13927.071428
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:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 13927.0714285
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 14:
28 goes into 200 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 13927.07142857
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.

In conclusion, the division gives 13927.07142857 with a balance of 4e-09.
