28453251 ÷ 789 
Let's see how many times 789 fits into 28453251.

Step 1:
789 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 789

Moving on to step 2:
When dividing 28 by 789, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 789

Step 3:
When dividing 284 by 789, we get 0 with a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 284 leaves us with 284.
Fetch the next digit (5) from the dividend, attach it to 284 and continue: 2845 / 789

On to step 4:
2845 divided by 789 is 3 with a remainder of 478.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2367 from 2845 leaves us with 478.
Append the next digit (3) from the dividend to 478 and continue with: 4783 / 789

Let's proceed to step 5:
789 goes into 4783 6 times with a remainder of 49.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 4734 from 4783 to get 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 789

Step 6:
When dividing 492 by 789, we get 0 with a remainder of 492.
The number 0 becomes the next digit in our result. 
Result so far: 360.0
Deduct 0 from 492 and we're left with 492.
Grab the next digit (5) from the dividend, add it to 492, then carry on: 4925 / 789

Step 7:
789 can be fit into 4925 6 times, resulting in a remainder of 191.
Write down 6 as next digit of the result. 
Result so far: 3606.0
If we subtract 4734 from 4925, we get 191.
Bring next digit (1) of the dividend behind the 191 and repeat the process: 1911 / 789

Advancing to step 8:
789 goes into 1911 2 times with a remainder of 333.
The number 2 becomes the next digit in our result. 
Result so far: 36062.0
Subtracting 1578 from 1911 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Moving on to step 9:
789 goes into 3330 4 times with a remainder of 174.
The number 4 becomes the next digit in our result. 
Result so far: 36062.4
Subtract 3156 from 3330 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 10:
1740 divided by 789 is 2 with a remainder of 162.
Record the quotient 2 as the next digit in the result. 
Result so far: 36062.42
Subtracting 1578 from 1740 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 11:
789 goes into 1620 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 36062.422
Subtract 1578 from 1620 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 36062.422 with a remainder of 0.0042.
