We're dividing 908439 by 28 
We're looking to find how many times 28 goes into 908439.

Step 1:
The number 28 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 28

On to step 2:
90 divided by 28 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 6 after subtracting 84 from 90.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 28

Going ahead to step 3:
The number 28 fits into 68 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtracting 56 from 68 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 28

Let's proceed to step 4:
When dividing 124 by 28, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
The remainder is 12 after subtracting 112 from 124.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 28

Advancing to step 5:
123 divided by 28 is 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 3244.0
Subtract 112 from 123 to get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 28

On to step 6:
When dividing 119 by 28, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 32444.0
Subtract 112 from 119 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
28 goes into 70 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 32444.2
The remainder is 14 after subtracting 56 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
140 divided by 28 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 32444.25
Subtract 140 from 140 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 28, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32444.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32444.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 32444.25, and the remainder is 0.0.
