We divide 50721 by 1
We want to figure out the number of times 50721 can be divided by 1.

Going ahead to step 1:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 5 from 5, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Going ahead to step 2:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Advancing to step 3:
1 goes into 7 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 507.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Advancing to step 4:
If we divide 2 by 1, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 5072.0
Deduct 2 from 2 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Going ahead to step 5:
When dividing 1 by 1, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 50721.0
The remainder is 0 after subtracting 1 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 50721.0
Deduct 0 from 0 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.

Let's proceed to step 7:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50721.0
Subtracting 0 from 0 leaves us 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 result is 50721.0 with a remainder of 0.0.
