We look at the division of 743597 by 18 
Let's see how many times 18 fits into 743597.

Let's proceed to step 1:
18 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 18

On to step 2:
74 divided by 18 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 2 after subtracting 72 from 74.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 18

Going ahead to step 3:
When dividing 23 by 18, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 18 from 23 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 18

Moving on to step 4:
When dividing 55 by 18, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 413.0
If we take 54 away from 55, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 18

Going ahead to step 5:
18 goes into 19 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 4131.0
If we take 18 away from 19, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 18

Moving on to step 6:
When dividing 17 by 18, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 41310.0
Subtracting 0 from 17 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
When dividing 170 by 18, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 41310.9
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 41310.94
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 18 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 41310.944
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 41310.944, and the remainder is 0.0008.
