We look at the division of 726842 by 18 
We want to figure out the number of times 726842 can be divided by 18.

Advancing to step 1:
If we divide 7 by 18, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 18

Advancing to step 2:
72 divided by 18 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 72 away from 72, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 18

On to step 3:
18 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 18

Step 4:
18 can be fit into 68 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 403.0
Subtracting 54 from 68 leaves us with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 18

Advancing to step 5:
When dividing 144 by 18, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 4038.0
Subtracting 144 from 144 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 18

Going ahead to step 6:
When dividing 2 by 18, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 40380.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
18 goes into 20 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 40380.1
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
18 can be fit into 20 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 40380.11
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 40380.11, and the remainder is 0.002.
