We're dividing 402989 by 28 
We're looking to find how many times 28 goes into 402989.

Let's proceed to step 1:
The number 28 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 28

On to step 2:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 28 from 40 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 28

Going ahead to step 3:
28 goes into 122 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 112 from 122, we get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 28

Moving on to step 4:
28 can be fit into 109 3 times, resulting in a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 143.0
If we take 84 away from 109, we end up with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 28

Advancing to step 5:
28 goes into 258 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 1439.0
The remainder is 6 after subtracting 252 from 258.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 28

Let's proceed to step 6:
When dividing 69 by 28, we get 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 14392.0
Deduct 56 from 69 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 28, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 14392.4
Subtracting 112 from 130 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
28 goes into 180 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 14392.46
Deduct 168 from 180 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.

On to step 9:
When dividing 120 by 28, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 14392.464
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.

Advancing to step 10:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 14392.4642
Deduct 56 from 80 and we're left 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.

Moving on to step 11:
If we divide 240 by 28, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 14392.46428
If we take 224 away from 240, 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.

On to step 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 14392.464285
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.

Let's proceed to step 13:
200 divided by 28 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 14392.4642857
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.

Step 14:
If we divide 40 by 28, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 14392.46428571
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.

The final result is 14392.46428571 with a remainder of 1.2e-08.
