We're dividing 721100 by 1 
Our goal is to divide 721100 by 1.

On to step 1:
If we divide 7 by 1, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 7 from 7 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Advancing to step 2:
1 goes into 2 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 721.0
Subtract 1 from 1 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

On to step 4:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 7211.0
If we subtract 1 from 1, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Going ahead to step 5:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72110.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Going ahead to step 6:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 721100.0
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.

Let's proceed to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 721100.0
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.

Moving on to step 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 721100.0
If we take 0 away from 0, 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.

Our division results in 721100.0 with a remaining 0.0.
