258744 ÷ 50 
We want to figure out the number of times 258744 can be divided by 50.

Step 1:
50 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 50

Let's proceed to step 2:
The number 50 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 50

Moving on to step 3:
50 can be fit into 258 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 250 from 258 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 50

Moving on to step 4:
87 divided by 50 is 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 51.0
The remainder is 37 after subtracting 50 from 87.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 50

Going ahead to step 5:
The number 50 fits into 374 7 times, leaving a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 517.0
If we subtract 350 from 374, we get 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 50

Advancing to step 6:
If we divide 244 by 50, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 5174.0
If we take 200 away from 244, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
50 can be fit into 440 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 5174.8
If we subtract 400 from 440, we 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 8:
50 can be fit into 400 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 5174.88
If we take 400 away from 400, 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.

The final outcome is 5174.88, with a leftover of 0.0.
