Let's divide 51243944 by 50
We want to figure out the number of times 51243944 can be divided by 50.

On to step 1:
50 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 50

Step 2:
When dividing 51 by 50, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 50 from 51 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 50

Going ahead to step 3:
50 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 50

Step 4:
When dividing 124 by 50, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we take 100 away from 124, we end up with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 50

Let's proceed to step 5:
50 goes into 243 4 times with a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 1024.0
If we take 200 away from 243, we end up with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 50

Let's proceed to step 6:
50 goes into 439 8 times with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 10248.0
The remainder is 39 after subtracting 400 from 439.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 50

On to step 7:
394 divided by 50 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 102487.0
Subtracting 350 from 394 leaves us with 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 50

Going ahead to step 8:
444 divided by 50 is 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 1024878.0
Deduct 400 from 444 and we're left 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.

Let's proceed to step 9:
50 can be fit into 440 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 1024878.8
Deduct 400 from 440 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 50 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1024878.88
If we subtract 400 from 400, 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 1024878.88, with a leftover of 0.0.
