Let's divide 721926 by 18
We want to figure out the number of times 721926 can be divided by 18.

Moving on to step 1:
If we divide 7 by 18, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 18

Let's proceed to step 2:
18 goes into 72 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 72 from 72 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 18

Step 3:
18 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 18

Step 4:
When dividing 19 by 18, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 401.0
If we subtract 18 from 19, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 18

On to step 5:
When dividing 12 by 18, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 4010.0
If we subtract 0 from 12, we get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 18

Moving on to step 6:
If we divide 126 by 18, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 40107.0
If we subtract 126 from 126, 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.

On to step 7:
18 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40107.0
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.

Advancing to step 8:
0 divided by 18 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40107.0
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 40107.0 with a remainder of 0.0.
