803963 divided by 48 
We want to figure out the number of times 803963 can be divided by 48.

Moving on to step 1:
48 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 48

Moving on to step 2:
80 divided by 48 is 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 48 from 80, we get 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 48

Step 3:
The number 48 fits into 323 6 times, leaving a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 288 from 323 to get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 48

Moving on to step 4:
48 can be fit into 359 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 167.0
The remainder is 23 after subtracting 336 from 359.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 48

Going ahead to step 5:
The number 48 fits into 236 4 times, leaving a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 1674.0
If we take 192 away from 236, we end up with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 48

Step 6:
48 can be fit into 443 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 16749.0
Subtracting 432 from 443 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
110 divided by 48 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 16749.2
Deduct 96 from 110 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
The number 48 fits into 140 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 16749.22
Subtract 96 from 140 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 16749.22 and a remainder of 0.044.
