We divide 721188 by 1
We want to divide 721188 by 1.

Advancing to step 1:
1 goes into 7 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 7 from 7 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Moving on to step 2:
2 divided by 1 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 2 from 2, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 721.0
If we subtract 1 from 1, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Step 4:
1 divided by 1 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 7211.0
The remainder is 0 after subtracting 1 from 1.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Let's proceed to step 5:
When dividing 8 by 1, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 72118.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Moving on to step 6:
If we divide 8 by 1, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 721188.0
The remainder is 0 after subtracting 8 from 8.
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.
The next digit of our result is 0. 
Result so far: 721188.0
If we subtract 0 from 0, 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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 721188.0
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 final result is 721188.0 with a remainder of 0.0.
