We look at the division of 50815875 by 42 
We want to figure out the number of times 50815875 can be divided by 42.

Going ahead to step 1:
42 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
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 42

Moving on to step 2:
If we divide 50 by 42, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 50 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 42

Step 3:
When dividing 88 by 42, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 84 from 88 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 42

Advancing to step 4:
The number 42 fits into 41 0 times, leaving a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 42

Going ahead to step 5:
When dividing 415 by 42, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 1209.0
If we subtract 378 from 415, we get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 42

Going ahead to step 6:
The number 42 fits into 378 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 12099.0
If we take 378 away from 378, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 42

Advancing to step 7:
42 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 120990.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 42

Moving on to step 8:
The number 42 fits into 75 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1209901.0
Deduct 42 from 75 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
If we divide 330 by 42, we get 7 and a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 1209901.7
Deduct 294 from 330 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
360 divided by 42 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1209901.78
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
When dividing 240 by 42, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1209901.785
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 1209901.7857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1209901.78571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 1209901.785714
If we subtract 168 from 180, 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.

Let's proceed to step 15:
If we divide 120 by 42, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 1209901.7857142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1209901.78571428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 1209901.78571428, and the remainder is 2.4e-08.
