Let's divide 643754 by 18
We want to divide 643754 by 18.

On to step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 18

Advancing to step 2:
The number 18 fits into 64 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 54 from 64, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 18

Let's proceed to step 3:
If we divide 103 by 18, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 90 from 103 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 18

Step 4:
The number 18 fits into 137 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 357.0
Deduct 126 from 137 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 18

Step 5:
115 divided by 18 is 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 3576.0
Deduct 108 from 115 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 18

Let's proceed to step 6:
When dividing 74 by 18, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 35764.0
If we subtract 72 from 74, 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.

Going ahead to step 7:
If we divide 20 by 18, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 35764.1
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.

Going ahead to step 8:
When dividing 20 by 18, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 35764.11
If we take 18 away from 20, we end up 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 final result is 35764.11 with a remainder of 0.002.
