51647449 ÷ 48 
We're looking to find how many times 48 goes into 51647449.

On to step 1:
If we divide 5 by 48, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 48

On to step 2:
If we divide 51 by 48, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 48 from 51.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 48

Let's proceed to step 3:
48 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 36 after subtracting 0 from 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 48

Step 4:
When dividing 364 by 48, we get 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we take 336 away from 364, we end up with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 48

Let's proceed to step 5:
287 divided by 48 is 5 with a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 1075.0
The remainder is 47 after subtracting 240 from 287.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 48

Going ahead to step 6:
48 goes into 474 9 times with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 10759.0
Deduct 432 from 474 and we're left with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 48

On to step 7:
If we divide 424 by 48, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 107598.0
The remainder is 40 after subtracting 384 from 424.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 48

Let's proceed to step 8:
409 divided by 48 is 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 1075988.0
If we subtract 384 from 409, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
48 can be fit into 250 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1075988.5
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 48, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 1075988.52
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
48 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1075988.52
Subtract 0 from 40 to 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.

Going ahead to step 12:
The number 48 fits into 400 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 1075988.5208
Subtracting 384 from 400 leaves us 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.

On to step 13:
48 goes into 160 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 1075988.52083
Subtracting 144 from 160 leaves us 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.

On to step 14:
When dividing 160 by 48, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 1075988.520833
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 1075988.520833 with a remainder of 1.6e-06.
