We divide 731641 by 18
Our goal is to divide 731641 by 18.

Advancing to step 1:
18 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 18

Going ahead to step 2:
18 goes into 73 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 72 from 73 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 18

Let's proceed to step 3:
18 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 18

Advancing to step 4:
18 can be fit into 116 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 406.0
Subtracting 108 from 116 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 18

Going ahead to step 5:
When dividing 84 by 18, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4064.0
Subtract 72 from 84 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 18

Step 6:
121 divided by 18 is 6 with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 40646.0
Deduct 108 from 121 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 18, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 40646.7
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 18 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 40646.72
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 40646.722
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 40646.722, with a leftover of 0.0004.
