53991 divided by 24 
We're looking to find how many times 24 goes into 53991.

Going ahead to step 1:
The number 24 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 24

Moving on to step 2:
24 can be fit into 53 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 5 after subtracting 48 from 53.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 24

On to step 3:
24 goes into 59 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 48 from 59 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 24

On to step 4:
24 goes into 119 4 times with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 224.0
Subtracting 96 from 119 leaves us with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 24

Going ahead to step 5:
The number 24 fits into 231 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 2249.0
Subtract 216 from 231 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 6:
24 can be fit into 150 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 2249.6
If we take 144 away from 150, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
24 goes into 60 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2249.62
If we subtract 48 from 60, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
24 can be fit into 120 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2249.625
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
24 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2249.625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 24 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2249.625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 2249.625, with a leftover of 0.0.
