Let's divide 840263 by 18
Let's see how many times 18 fits into 840263.

Going ahead to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 18

Advancing to step 2:
84 divided by 18 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 12 after subtracting 72 from 84.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 18

Going ahead to step 3:
When dividing 120 by 18, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 108 away from 120, we end up with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 18

Going ahead to step 4:
122 divided by 18 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 466.0
Subtract 108 from 122 to get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 18

Moving on to step 5:
The number 18 fits into 146 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 4668.0
If we subtract 144 from 146, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 18

Going ahead to step 6:
18 goes into 23 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 46681.0
Deduct 18 from 23 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 divided by 18 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 46681.2
Deduct 36 from 50 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
18 goes into 140 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 46681.27
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
When dividing 140 by 18, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 46681.277
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 46681.277 with a balance of 0.0014.
