447444 ÷ 51 
Our goal is to divide 447444 by 51.

Step 1:
The number 51 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 take 0 away from 4, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 51

Going ahead to step 2:
51 can be fit into 44 0 times, resulting in a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 51

Step 3:
If we divide 447 by 51, we get 8 and a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 408 from 447, we get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 51

On to step 4:
If we divide 394 by 51, we get 7 and a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtract 357 from 394 to get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 51

Going ahead to step 5:
374 divided by 51 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 877.0
Deduct 357 from 374 and we're left with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 51

Going ahead to step 6:
When dividing 174 by 51, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 8773.0
If we subtract 153 from 174, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
If we divide 210 by 51, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 8773.4
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 8773.41
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 51, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 8773.411
If we take 51 away from 90, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 8773.411, with a leftover of 0.0039.
