We're dividing 448246 by 51 
We want to figure out the number of times 448246 can be divided by 51.

On to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 51

On to step 2:
The number 51 fits into 44 0 times, leaving a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 51

Going ahead to step 3:
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: 8.0
Deduct 408 from 448 and we're left with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 51

Moving on to step 4:
The number 51 fits into 402 7 times, leaving a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtracting 357 from 402 leaves us with 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 51

Step 5:
454 divided by 51 is 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 878.0
The remainder is 46 after subtracting 408 from 454.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 51

Going ahead to step 6:
When dividing 466 by 51, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 8789.0
Subtracting 459 from 466 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.

On to step 7:
51 can be fit into 70 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 8789.1
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.

Advancing to step 8:
The number 51 fits into 190 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 8789.13
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 8789.137
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.

On to step 10:
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: 8789.1372
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 51 fits into 280 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 8789.13725
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
51 goes into 250 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 8789.137254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
460 divided by 51 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 8789.1372549
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
The number 51 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8789.1372549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 8789.1372549 and a remainder of 1e-08.
