126783 divided by 18 
Our goal is to divide 126783 by 18.

Advancing to step 1:
1 divided by 18 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 18

Let's proceed to step 2:
18 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 18

Advancing to step 3:
18 goes into 126 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 0 after subtracting 126 from 126.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 18

Step 4:
When dividing 7 by 18, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 70.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 18

Moving on to step 5:
The number 18 fits into 78 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 704.0
The remainder is 6 after subtracting 72 from 78.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 18

Let's proceed to step 6:
18 goes into 63 3 times with a remainder of 9.
The next digit of our result is 3. 
Result so far: 7043.0
If we take 54 away from 63, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 18 fits into 90 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7043.5
Subtracting 90 from 90 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.

Advancing to step 8:
0 divided by 18 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7043.5
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.

Step 9:
18 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7043.5
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.

After the division, we end up with 7043.5 and a remainder of 0.0.
