642431 ÷ 50 
Let's see how many times 50 fits into 642431.

Step 1:
The number 50 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 50

Advancing to step 2:
The number 50 fits into 64 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 50 away from 64, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 50

Let's proceed to step 3:
50 goes into 142 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 100 from 142 leaves us with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 50

Let's proceed to step 4:
When dividing 424 by 50, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 400 from 424 leaves us with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 50

Moving on to step 5:
243 divided by 50 is 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 1284.0
If we take 200 away from 243, we end up with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 50

Moving on to step 6:
50 goes into 431 8 times with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 12848.0
The remainder is 31 after subtracting 400 from 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
310 divided by 50 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 12848.6
The remainder is 10 after subtracting 300 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
50 can be fit into 100 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 12848.62
Deduct 100 from 100 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.

Moving on to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12848.62
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12848.62
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.

The quotient of the division is 12848.62, and the remainder is 0.0.
