448228 ÷ 51 
We're looking to find how many times 51 goes into 448228.

Going ahead to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 51

Advancing to step 2:
If we divide 44 by 51, we get 0 and a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 51

Moving on to step 3:
51 can be fit into 448 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 408 from 448 leaves us with 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 51

Going ahead to step 4:
When dividing 402 by 51, we get 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 357 away from 402, we end up with 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 51

Advancing to step 5:
51 goes into 452 8 times with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 878.0
Subtract 408 from 452 to get 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 51

On to step 6:
If we divide 448 by 51, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 8788.0
If we subtract 408 from 448, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 8788.7
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 8:
430 divided by 51 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 8788.78
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
If we divide 220 by 51, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 8788.784
Deduct 204 from 220 and we're left 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.

Moving on to step 10:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8788.7843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
If we divide 70 by 51, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 8788.78431
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
The number 51 fits into 190 3 times, leaving a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 8788.784313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 8788.7843137
Deduct 357 from 370 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.

Let's proceed to step 14:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 8788.78431372
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 8788.78431372 and a remainder of 2.8e-08.
