863438 ÷ 18 
We want to divide 863438 by 18.

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.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 18

Going ahead to step 2:
86 divided by 18 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
If we take 72 away from 86, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 18

Step 3:
The number 18 fits into 143 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Deduct 126 from 143 and we're left with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 18

On to step 4:
If we divide 174 by 18, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 479.0
Subtracting 162 from 174 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 18

Advancing to step 5:
When dividing 123 by 18, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 4796.0
Deduct 108 from 123 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 18

Step 6:
When dividing 158 by 18, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 47968.0
The remainder is 14 after subtracting 144 from 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
18 goes into 140 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 47968.7
If we take 126 away from 140, we end up 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.

Advancing to step 8:
140 divided by 18 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 47968.77
If we take 126 away from 140, we end up 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 47968.77 with a balance of 0.014.
