28345287 ÷ 989 
We want to figure out the number of times 28345287 can be divided by 989.

Moving on to step 1:
989 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 989

Moving on to step 2:
If we divide 28 by 989, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 989

Step 3:
The number 989 fits into 283 0 times, leaving a remainder of 283.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 283 after subtracting 0 from 283.
Include the next digit (4) from the dividend after 283, then repeat: 2834 / 989

Going ahead to step 4:
989 can be fit into 2834 2 times, resulting in a remainder of 856.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1978 away from 2834, we end up with 856.
Fetch the next digit (5) from the dividend, attach it to 856 and continue: 8565 / 989

On to step 5:
The number 989 fits into 8565 8 times, leaving a remainder of 653.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 7912 away from 8565, we end up with 653.
Bring next digit (2) of the dividend behind the 653 and repeat the process: 6532 / 989

Step 6:
6532 divided by 989 is 6 with a remainder of 598.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
The remainder is 598 after subtracting 5934 from 6532.
Append the next digit (8) from the dividend to 598 and continue with: 5988 / 989

Step 7:
989 goes into 5988 6 times with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 2866.0
Deduct 5934 from 5988 and we're left with 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 989

Let's proceed to step 8:
547 divided by 989 is 0 with a remainder of 547.
Write down 0 as next digit of the result. 
Result so far: 28660.0
Subtract 0 from 547 to get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Moving on to step 9:
When dividing 5470 by 989, we get 5 with a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 28660.5
Subtracting 4945 from 5470 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 10:
989 goes into 5250 5 times with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 28660.55
Subtracting 4945 from 5250 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The quotient of the division is 28660.55, and the remainder is 0.305.
