We look at the division of 51490 by 48 
Let's see how many times 48 fits into 51490.

Going ahead to step 1:
5 divided by 48 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 48

Going ahead to step 2:
48 can be fit into 51 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 48 from 51 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 48

Moving on to step 3:
If we divide 34 by 48, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 48

Advancing to step 4:
48 can be fit into 349 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 336 away from 349, we end up with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 48

Step 5:
The number 48 fits into 130 2 times, leaving a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 1072.0
The remainder is 34 after subtracting 96 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 6:
48 goes into 340 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 1072.7
Deduct 336 from 340 and we're left 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.

Advancing to step 7:
48 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1072.7
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 48, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1072.708
Deduct 384 from 400 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.

On to step 9:
48 goes into 160 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 1072.7083
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.

Going ahead to step 10:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 1072.70833
Deduct 144 from 160 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.

The final result is 1072.70833 with a remainder of 1.6e-05.
