52374 ÷ 21 
Our goal is to divide 52374 by 21.

Advancing to step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 21

Advancing to step 2:
21 can be fit into 52 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 42 from 52, we get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 21

Let's proceed to step 3:
21 can be fit into 103 4 times, resulting in a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 84 from 103 to get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 21

On to step 4:
197 divided by 21 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
Subtracting 189 from 197 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 21

Moving on to step 5:
84 divided by 21 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 2494.0
If we subtract 84 from 84, we 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 6:
0 divided by 21 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2494.0
If we take 0 away from 0, we end up 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.

Advancing to step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2494.0
If we subtract 0 from 0, we 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.

The final outcome is 2494.0, with a leftover of 0.0.
